Publication Policies

The following requirements will permit you to determine if you can submit a paper to an SPIE journal.

Significance: Contributions should be substantial and significant in content. We may decline to publish papers that report only incremental progress. Although a paper may be correct and appropriate for an SPIE journal, if it does not demonstrate, in the estimation of the reviewers and editor, sufficient new and important information to warrant publication, or provide a comprehensive review of the current state of the art, it will be declined. Manuscripts that are commercial in nature will not be considered.

Originality: Papers should describe the original work of the authors that has not been previously published in a refereed journal and is not currently under consideration for publication in another refereed journal. SPIE does not allow or sanction duplicate or concurrent submissions of a paper to more than one peer-reviewed journal. Any copying of text, figures, data, or results of other authors without giving credit is defined as plagiarism and is a breach of professional ethics. Such papers will be rejected and other penalties may be assessed. 

Double Publication: Papers should not report work that the author has already published in another refereed journal. This is also an ethical violation. Such papers will be rejected and other penalties may be assessed.

Previously Rejected Papers: If you are submitting a new version of a paper that was previously submitted to an SPIE journal and was declined, there is an entry on the submission form to indicate this. Follow the instructions there, and in a cover letter, indicate the paper number and title, and briefly describe the changes that have been made to warrant a new submission. Copies of rejected manuscripts are retained in the journal's editorial system.

Note: SPIE journal policy is that after a reject decision, resubmission of a manuscript will normally only be accepted after three months have elapsed since the decision date. This policy is intended to ensure that adequate time is available between the reject decision and resubmission to address the major changes and rewrite that are normally required to address the concerns leading to a reject decision.

Rejection by Another Journal: If the paper has been submitted to another journal and rejected, and if you believe that submission to one of SPIE's journals would be more appropriate, you are urged to take into account any comments or suggestion for improvement from your previous submission. Our reviewers will usually find the faults identified by previous reviewers.

Conference Proceedings Papers

Submissions to SPIE journals based on reports that have been submitted to or published in a conference proceedings should adhere to the following guidelines:

Distinction between proceedings and journal papers: Conference proceedings provide a vehicle for rapid reporting of ideas, techniques, and results. It is not uncommon for these reports to be somewhat incomplete and inconclusive. The purposes of proceedings papers range from snapshots of recent or continuing work to the reporting of a completed work or project. Journal papers are expected to be original, complete, and polished; to contain comparisons of theoretical and experimental results; and to include substantial conclusions and comprehensive references to other work.

Revision of conference proceedings manuscripts for journal submission: SPIE publication policy permits manuscripts based partly or entirely on scientific content previously reported in SPIE proceedings to be submitted to SPIE journals. In most cases, it is anticipated that the journal submission will represent a substantively expanded, refined, or otherwise revised manuscript relative to the related proceedings paper to fully satisfy the standards of significance, originality, and presentation quality that may result in acceptance through the journal peer review process. A manuscript submitted to an SPIE journal that incorporates minimal or no revisions over a prior or concurrent SPIE proceedings paper may be considered for publication in an SPIE journal and admitted into the peer-review process provided the submission fulfills the requirements of significance, originality, and completeness expected in a journal submission. SPIE does not consider publication of an accepted journal article based on a prior proceedings paper to constitute double publication.

Disclosure: If a manuscript (or portion of a manuscript) was previously published in a conference proceedings or is under consideration for publication in a conference proceedings, this information must be disclosed when the manuscript is initially submitted to an SPIE journal. Authors should also reference or acknowledge the prior proceedings paper within the submitted journal article.

Copyright: SPIE copyright policy permits authors to submit derivations of their proceedings papers to their journal of choice. Submissions to SPIE journals are permissible provided the other expectations described herein are satisfied. Authors submitting to journals published by other publishers should verify that publisher's copyright and submission policies. Authors wishing to submit papers that were presented at or published in a conference proceedings sponsored by organizations other than SPIE are responsible for adhering to the copyright policies related to that presentation or publication and are expected to disclose the prior presentation or publication history of the submission.

Journal submission format: All proceedings manuscripts submitted to an SPIE journal must be prepared according to the guidelines provided here.

SPIE Code of Ethics

The Mission/Vision Statement of SPIE, the International Society for Optics and Photonics states that SPIE partners with researchers, educators, and industry to advance light-based research and technologies for the betterment of the human condition. It is the purpose of this statement to advance this vision by presenting ethical guidelines for society members, collaborators, and participants to abide by in their professional lives.

Professional Behavior

1. Discrimination based on race, religion, gender, age, disability, or sexual orientation is not acceptable.
2. Individual and public safety and welfare should be considered paramount in performance of professional duties.
3. Real and potential conflict of interest should be avoided and disclosed to all impacted parties when it cannot be avoided.
4. Technical knowledge and skills should be kept up-to-date and work should be performed in areas of competency.
5. Public statements should be realistic and issued in an objective and truthful manner based on available data.
6. Professional confidentiality should be maintained.
7. Accomplishments, publications, professional honors and titles should be accurately reported.

Read the entire SPIE Code of Ethics.

SPIE is a member of the Committee on Publication Ethics (COPE). COPE has published a position statement setting out international standards for responsible research publication for authors here. 

Authorship

Authorship should be limited to those who have made a significant contribution to the concept, design, execution or interpretation of the research study. All those who have made significant contributions should be offered the opportunity to be listed as authors. Other individuals who have contributed to the study should be acknowledged, but not identified as authors. The sources of financial support for the project should be disclosed.

All collaborators share some degree of responsibility for any paper they coauthor. Some coauthors have responsibility for the entire paper as an accurate, verifiable, report of the research. These include, for example, coauthors who are accountable for the integrity of the critical data reported in the paper, carry out the analysis, write the manuscript, present major findings at conferences, or provide scientific leadership for junior colleagues.

Coauthors who make specific, limited, contributions to a paper are responsible for them, but may have only limited responsibility for other results. While not all coauthors may be familiar with all aspects of the research presented in their paper, all collaborations should have in place an appropriate process for reviewing and ensuring the accuracy and validity of the reported results, and all coauthors should be aware of this process.

Every coauthor should have the opportunity to review the manuscript before its submission. All coauthors have an obligation to provide prompt retractions or correction of errors in published works. Any individual unwilling or unable to accept appropriate responsibility for a paper should not be a coauthor.

Collaborations are expected to have a process to archive and verify the research record; to facilitate internal communication and allow all authors to be fully aware of the entire work; and respond to questions concerning the joint work and enable other responsible scientists to share the data. All members of a collaboration should be familiar with, and understand, the process.

Plagiarism

Plagiarism constitutes unethical scientific behavior and is never acceptable. Proper acknowledgement of the work of others used in a research project must always be given. Further, it is the obligation of each author to provide prompt retractions or corrections of errors in published works.

It should be recognized that honest error is an integral part of the scientific enterprise. It is not unethical to be wrong, provided that errors are promptly acknowledged and corrected when they are detected.

SPIE uses the Crossref Similarity Check plagiarism screening service to detect instances of overlapping and similar text in submitted manuscripts. Crossref Similarity Check is a multipublisher initiative to screen published and submitted content for originality.

Conflict of Interest

Real and potential conflict of interest should be avoided and disclosed to all impacted parties when it cannot be avoided.

There are many professional activities of scientists and engineers that have the potential for a conflict of interest. Any professional relationship or action that may result in a conflict of interest must be fully disclosed. When objectivity and effectiveness cannot be maintained, the activity should be avoided or discontinued.

Authors should clearly identify in the manuscript all financial and material support for their research and work under a Disclosures header before the Acknowledgments. If the authors have no relevant financial interests in the manuscript and no other potential conflicts of interest to disclose, a statement to this effect should also be included in the manuscript.

A helpful form with guidelines for generating a disclosure statement is available from the International Committee of Medical Journal Editors website (see http://www.icmje.org/conflicts-of-interest/). This form should not be uploaded with a manuscript submission; it is only a tool to help authors generate a disclosure statement.

Use of Human Subjects and Animals

SPIE expects all authors to observe internationally accepted principles and practices related to the ethical conduct of research involving the use of human subjects or animals. A brief statement must be included in the manuscript identifying the institutional oversight or licensing body that approved the studies. For studies involving human subjects, a statement must also be included confirming that informed consent was either obtained from all subjects or this requirement was waived by the oversight body.

Authors must obtain written permission from the subject (or parent/guardian, if the subject is a minor child) to publish a photograph with an identifiable human face. Such photographs should be used only when scientifically relevant.

Overview

Manuscripts should be submitted in English, and the presentation should be as succinct as comprehension will permit. Manuscripts are reviewed and refereed. Those accepted for publication are edited for conformance to the journal's style.

How to Write a Good Scientific Paper by Chris Mack is a useful guide on writing for a peer-reviewed journal. Click here to download the full PDF of this free SPIE ebook.

For peer review, manuscripts should be submitted with the figures/tables and their captions incorporated into the same file as the manuscript text. However, upon first revision or acceptance, authors will be asked to submit individual figure files and a properly formatted manuscript for use in production.

SPIE journals typically allow only one round of major revision. Authors should carefully address all reviewer comments when submitting a revised manuscript. 

Claims of "new" or "novel" work or of being the "first" to report on a topic should be avoided unless they can be fully substantiated.

Cover Letter

Authors are required to include a separate cover letter with their submission explaining the significance and novelty of the work, the problem that is being addressed, and why the manuscript belongs in this journal. This cover letter sample (.docx) can be used as a template.

English Language Editing

If you are not a native English speaker, SPIE recommends that your manuscript be professionally edited prior to submission. SPIE authors will receive a 15% discount off the language editing services provided by Editage, an independent editorial service recommended by SPIE. Please note that use of this service does not guarantee editorial acceptance by an SPIE journal. More detailed information can be found at editage.com/spie.

Manuscript Types

Letter: A short technical communication of significant interest intended for rapid publication in the JBO Letters section of the journal. The manuscript length may not exceed four printed journal pages. This corresponds to approximately 4000 words (excluding title, abstract, and author information); figures will further reduce the maximum word content.  A page length estimator template is available to help determine final typeset page length.

A Letters page length template (.docx) is available for your convenience. Please note that this template should not be used for layout and formatting of your manuscript. It should only be used to roughly determine the final length of a typeset paper. To use this template, copy and paste the text of your abstract, paper body, and references where shown, and do not change font or margins. Insert and size your figures and captions to determine if the paper will fit within the four-page limit.

Regular Paper: A full-length manuscript presenting original work intended as a regular contribution to the journal.

Special Section Paper: A full-length manuscript presenting original work intended for submission to a special topical section organized by a guest editor.

Review Paper: An article reviewing a particular topic or field. Review papers are typically invited papers written by a highly regarded expert in the field. Review articles summarize progress made in a particular research or development area during a specified period and summarize the current state of the art.

Tutorial: A tutorial is an introductory and systematic description of a technology or a research topic. Tutorials should be accessible to general readers of JBO and may include homework problems.

Outlook: A visionary type of paper that takes a speculative look at where a technology or a research area might be heading. Of particular interest are the prospects in the next 5-15 years. Outlook papers should include a brief overview followed by predictions for the future and may occupy 5-10 printed pages in the journal. Potential authors are encouraged to contact the Editor-in-Chief before writing the manuscript.

Perspective: A needs-based assessment of a field of medicine where an expert review is provided, with the goal of identifying the missing factors or challenges that might be addressable by optical technologies or methods. The focus is on identifying the current state of the art and the problems in it, without an overt focus on proving the use of any particular technology. These articles are intentionally designed to help direct the field of biomedical optics to address the needs in current and future biomedical practice. Potential authors are encouraged to contact the Editor-in-Chief before writing the manuscript.

Manuscript Templates

To make your initial submission process as easy as possible, as well as to make it easier for the editors and referees to review your manuscript, for the initial submission we only require a single document containing the manuscript and figures, along with any supporting multimedia files. The document may be in MS Word, LaTeX, or PDF. The figures and their captions should be placed within the manuscript, near the first mention each figure in the text. Individual figure files and source manuscript files will then be requested in one of the acceptable formats upon revision. When submitting a revised manuscript, you may upload a single .zip file containing the manuscript and figure files.

Microsoft Word: A Microsoft Word template (.docx) is available to assist you with formatting. Use MathType for equations. Or, if using MS Word 2007 or later, the native equation editor can be used, but the document must be saved as .docx. Backsaving to .doc format will convert all equations to low-resolution graphics, which cannot be used for typesetting. Please note that all accepted papers are professionally typeset; the template is intended only as a guideline for author convenience, and it is not necessary to rigidly adhere to the format.

LaTeX: A LaTeX template (.zip) is available to assist you with formatting, or you can use the Overleaf authoring tool explained below. LaTeX manuscripts can be uploaded as a .zip file including the manuscript, locally compiled PDF, bibliography, and all referenced style files and figures; or, the files can be uploaded separately. Please include all style files that are referenced in the .tex manuscript (such as .cls, .bst, .sty, etc.). Upon submission, choose file type "Merged PDF" for the locally compiled PDF; select "Bibliography" for .bib files; and select "LaTeX Supplementary File" for .cls, .bst, . sty, and any other associated style files. Do not include the README.txt file in the upload. Please note that all accepted papers are professionally typeset; the template is intended only as a guideline for author convenience.

    The SPIE journal template is now available in the Overleaf authoring tool. Originally developed to simplify LaTeX authorship, this free online tool has numerous benefits, including:

• real-time collaboration between authors
• an intuitive user interface
• user support and LaTeX help
• easy document sharing and security options
• real-time preview of formatting and equations
• inline error warnings
• a rich-text mode that will look familiar to collaborators who are more comfortable authoring in Microsoft Word
• quick submission to an SPIE journal by following the link "Submit to SPIE Journals" at the top of the Overleaf template.

The SPIE Journal template can be found on Overleaf, along with helpful LaTeX tutorials and a free introductory course for authors who are new to Overleaf and LaTeX. If you encounter any problems using the SPIE LaTeX template on Overleaf, please contact their support team via https://www.overleaf.com/contact and they will help you resolve the issue.

Parts of a Manuscript

Title

The title of your paper should be descriptive and concise.

• Acronyms should be spelled out.
• Titles should not begin with the articles A, An, or The.
• Avoid use of the words "new" or "novel" in the title.

Authors and Affiliations

Provide full author names, including given name and family name. These names will be used in official databases and indexes. Initials are not allowed for the given name. Provide full affiliations, including institution, department, street address, city, postal code, and country. An email address should be provided for the corresponding author, and this person should be noted with a footnote.

Abstract

The abstract should be a summary of the paper and not an introduction (200 words maximum). Because the abstract may be used in abstracting journals, it should be self-contained (i.e., no numerical references) and substantive in nature, presenting concisely the objectives, methodology used, results obtained, and their significance. For further guidelines, please read the brief article titled "How to Write an Abstract," by Philip Koopman. (Courtesy of Philip Koopman, Carnegie Mellon University.) Abstracts should not make claims of novelty, as publication implies novelty.

Nontechnical Research Summary

The online submission form has an optional field to include a short nontechnical summary of your research (200 words maximum) and its potential applications. (This item does not need to be included in the actual manuscript file; you will be asked to add it on the submission form.) Nonspecialist readers should be able to understand the language used and the significance of the work. The summary should provide an accurate description of the importance of the research without overstating the potential impact of the paper. This research summary may be used by the journal for promotion of significant work.

Subject terms or keywords

Keywords are required. Please provide 3-6 keywords related to your paper.

Text

Type manuscript double-spaced, in a single column, using a readable font size (for example, 12-point type). Page numbers must be included. Please also add line numbering if you are submitting in LaTeX or PDF (line numbering will be automatically added to MS Word manuscripts by the submission system). Note the following style points:

• Journal style does not permit use of bold and italic font for emphasis; these styles should be reserved for formatting math. 
• Words should be spelled using American English. 
• Spell out all abbreviations and acronyms at first use. 
• Metric units should be used unless to do so is not feasible or would result in a serious loss of clarity. 
• Footnotes are not allowed.

Equations

Create equations using MathType or Equation Editor 3.0. If using Word 2007 or later, the native equation editor can be used, but the document must be saved as .docx. When equations built with Microsoft's Editor are back-saved to the .doc format, they are converted to low-resolution graphics and will not be usable for composition. To use MathType or the old Equation Editor 3.0, you will need to select Object on the Text section of the Insert tab and then select MathType/Equation Editor in the drop-down menu. Variables should be written in italic font.

Biographies

Biographies of authors are published with each paper. Manuscripts should include a brief professional biography not to exceed 75 words. Authors are also encouraged to update their online SPIE profile with their photograph and biography on our website at http://spie.org/profiles/home. This profile will be linked to the published paper. 

Appendices

Any figures, tables, or equations in Appendices should continue the numbering sequence established in the body of the paper. Appendices may not be comprised of only tables and figures; they must also include explanatory text and captions.

Disclosures

Conflicts of interest should be declared under a "Disclosures" header, above Acknowledgments. If the authors have no competing interests to declare, then a statement should be included declaring no conflicts of interest. For assistance generating a disclosure statement, see the form available from  the International Committee of Medical Journal Editors website: http://www.icmje.org/conflicts-of-interest/.

Acknowledgments/Funding Sources

Use this section to identify people who have aided the authors in accomplishing the work presented and to acknowledge sources of funding. Include grant numbers and the full name of the funding body. Funding information will be deposited to FundRef.

References

The purpose of a reference is to make the source easy for the reader to locate. To this end, each reference should provide as much information as is available. The basic elements of a reference include author names (including first initials), article/chapter title, journal or book title, volume number, issue number, page range, and year of publication. References are professionally copyedited on accepted manuscripts to conform to journal style, and authors do not need to spend a lot of time adapting references to the journal's reference format, so long as all of the required information is present.

References to published literature should be listed at the end of the manuscript and numbered consecutively in the order of their citation in the text. In-text citations can use superscript or bracketed reference numbers. Private communications or unpublished reports should be treated as references. Click here for sample book, journal, and Internet references. For references with three or fewer authors, list all authors. For references with four or more authors, list the first author only followed by "et al."

Books: Author(s) (list first and middle initials, then last name), book title in italic, publisher, city, and year published. (When citing a paper chapter in a book, list the chapter title in quotes, and the book title in italic, plus the page numbers.) Example: J. A. Hall, "Imaging tubes," Chap. 13 in The Infrared Handbook, W. W. Wolfe, G. J. Zissis, Eds., pp. 132-176, ERIM, Ann Arbor, MI (1978).

Journals: Author(s) (list first and middle initials, then last name), paper title in quotes, journal name in italic (abbreviate only well-known journals), volume and issue numbers, inclusive page numbers, and year published. Example: N. Bluzer and A. S. Jensen, "Current readout of infrared detectors," Opt. Eng. 26(3), 241-248 (1987).

Internet: Author (if stated), “Title of document,” Title of complete work (if relevant), date of online publication or last revision, (date of access, if known) [URL]. Example: J. D. Harrington and K. Barnstorff, "NASA tests software that may help increase flight efficiency, decrease aircraft noise," NASA, 15 December 2014 (accessed 29 January 2015). [http://www.nasa.gov/press/2014/december/nasa-tests-software-that-may-help-increase-flight-efficiency-decrease-aircraft/#.VMq3AfldVI5]

Artwork Preparation

Figures: must be submitted via the online submission system in EPS, TIFF, PNG, or PDF format. We cannot accept application files, i.e., Corel Draw, Microsoft Word, etc. Number all figures in the order that they appear in the text. All figure parts/panels must be labeled (a), (b), etc. Submit high-resolution figures. The quality of the published figure is only as good as the original file—it cannot be improved by the typesetter.

Color: All figures submitted in color will be published in color online without charge. Authors should submit a single color version of the figure. The black-and-white figure for print will be derived from the color file submitted by the author. Authors who choose to submit color figures are responsible for ensuring that the captions and descriptions in the text are suitable for both the color online and black-and-white print versions of the journal, and that the figure itself will be readable in both versions. This includes making line art readable in grayscale. Figures must be prepared according to the guidelines below.

Authors who wish to have color figures published in the print journal will incur color printing charges. Because print quantities have decreased with the dominance of online publication, SPIE has reduced the color fee to $200 for each color figure to pass those savings onto the author. Authors who would like figures printed in color must complete and return a Color Authorization Form upon acceptance of their manuscript.

Figure Permissions: If the figure is derived from a previously published image, the author must obtain permission from the original copyright holder, who may be the publisher and/or the author. Once permission is granted, the figure caption should include the line "Reproduced with permission, courtesy of [copyright owner]," or the publisher's required copyright statement. Many permissions can be obtained via the Copyright Clearance Center.

Figure Requirements:

Tables

Tables should be built in Word, Excel (embedded in Word), or LaTeX. They should not contain graphics. Tables containing images must be numbered as figures. Colored fonts will not appear in the typeset version, so bold and italic should be used for emphasis instead. Explain use of bold or italic in the caption or table footnote. Do not use shading. Very large tables may be vertically oriented, or they may span multiple typeset pages. A caption must be included with the table.

Multimedia

Multimedia files must be submitted as an integral part of the paper. Supplemental multimedia material is not accepted.

Video Requirements:

Acceptable file formats include:

• QuickTime nonstreaming video (.qt or .mov)
• MPEG (.mpg or .mp4)

The acceptable file formats outlined above are playable using standard media players such as QuickTime and Windows Media Player. Media players should be used to check file properties and image/sound quality prior to submission.

Because the speed of Internet connection varies, a recommended maximum size for each video file is 10-12 MB.

If videos are included as part of an existing figure, they should be described and identified within the figure caption. The media file type and file size should be included in parentheses at the end of the caption; e.g., (MPEG, 2.5 MB). For example:

Fig. 1 Confocal microscopic images of red blood cells in (a) an isotonic buffer (Video 1) and (b) a hypertonic buffer (Video 2) in three different viewing projections (Video 1, MPEG, 3.1 MB; Video 2, MPEG, 4.2 MB).

Stand-alone videos should be accompanied by a representative still image. This image should be treated as a figure, numbered in sequence, and submitted in one of the accepted figure file formats. A caption describing the content of the video file is required, similar to a typical figure caption. For example:

Fig. 4 Photodynamic therapy response of the targeted region (QuickTime, 5 MB).

Supplementary Material and Code

Supplementary Material

SPIE journals do not accept or publish supplemental materials that are not an integral part of the manuscript. However, certain types of supplementary material may benefit the reader's understanding of the work and be published as part of the manuscript, either in an appendix or as an accompanying multimedia file. Examples of such material include multipage tables, 3D and interactive multimedia, and software instructions. If you wish to include supplementary materials in your manuscript, please contact the journal staff at journals@spie.org for guidance. All such supplementary material will be peer reviewed, and the journal editor has the final authority to decide whether the supplementary material is acceptable. SPIE journals do not publish large datasets at this time. However, authors may reference large datasets hosted on external websites (such as an official data center/archive or a university repository) by including a link to the site in the manuscript.

Code

Software and code are often essential for reproducibility and reuse in new research. Software and code can be easily incorporated into your SPIE journal manuscript via Code Ocean. Uniquely, Code Ocean allows you to upload the code, together with its dependencies and any data, so it is executable. Code Ocean supports more than 10 different programming languages. The Code Ocean platform provides open access to the published software code, which can be viewed and downloaded by everyone for free. Users can execute all published code in the cloud, without installing anything on their personal computer. Code Ocean is SPIE's recommended platform for sharing code, but other repositories, such as GitHub, Zenodo, etc., may be similarly used as a hosting platform.

  Manuscripts that include code, e.g., an algorithm implementation or analysis, hosted by an external website should mention that code and the name of the repository in the text of the paper or figure caption:

Example 1:
The archived version of the code can be freely accessed and executed through Code Ocean.  

Example 2:
The code used to generate the results and figures is available in a Github repository.

If you intend to upload code to Code Ocean, you may do so before or after article acceptance, but prior to publication. Authors of papers that mention code/software on Code Ocean will receive instructions on how to link the code to the article in the author proofs.

Peer Review Process

All submissions are screened to ensure they meet basic standards of manuscript presentation and are also processed through Crossref Similarity Check. Manuscripts are then evaluated by the editor-in-chief (EiC) and/or a designated editorial board member (EBM) to ensure they meet the journal's rigorous scientific standards and are eligible for peer review. Manuscripts that meet these criteria are single-blind reviewed by at least two referees selected by the EBM based on their expertise in the topic. The referees provide detailed comments and recommendations to help the EBM arrive at the appropriate editorial decision. Revised manuscripts are evaluated by the EBM and are sent back to the original referees in the case of major revisions. The EiC has the ultimate authority to accept or reject a submission.

Authors may appeal to the EBM or EiC to reconsider a rejection decision if they believe that the reviewers have seriously misjudged the manuscript. All appeals will be given careful consideration. The EBM and/or EiC will determine if further consideration is merited or if the original decision should stand.

Submissions from editors or members of the editorial board are handled by an editorial board member who is not connected with the manuscript to ensure that such submissions receive an objective and unbiased evaluation. Information about the review process for such submissions is redacted from the view of any editors or editorial board members who are authors of the paper within the journal's online submission and review system.

Open Access

JBO will become a fully open access journal in January 2019. Beginning with submissions received on or after 1 July 2018, authors of accepted papers will be required to pay an article processing charge of $1675. Discounts may apply.  Read more about the fee, discounts, and license for open access publication.

Until July 1^st, JBO authors have the choice to publish with open access for a flat fee, or publish under access control for no fee. Details can be found at the link above.

Copyright and Publication Licenses

Until 1 January 2019, papers may be published under traditional SPIE copyright or the Creative Commons CC-BY attribution license.

Authors who choose to pay the open access fee will retain copyright and the publisher (SPIE) will license these articles under a Creative Commons Attribution license (CC BY).

Authors who do not pay the open access fee will have their papers published under the SPIE Transfer of Copyright agreement.

Following 1 January 2019, all JBO papers will be published under the Creative Commons Attribution 4.0 license.

Author Proofs

Accepted papers are immediately sent into production, where they are professionally copyedited and typeset in XML. It usually takes 10-12 days after acceptance to generate the first proof. The corresponding author will be notified by email when the proof is ready to review. Changes should be kept to a minimum. Additions or subtractions of large portions of text may require re-review, and numerous changes may incur article processing charges.

Promote Your Research

SPIE invites you to register for Kudos. Kudos tools are designed to help increase your readership and citations. This service is completely free to use. You can also view metrics associated with your publications' performance on Kudos. According to a study by Kudos, use of the Kudos toolkit by researchers to share their published articles correlates to 23% higher downloads. To register to see your metrics, and to try out the Kudos tools, go to https://www.growkudos.com/register.

Here are some additional ways you could publicize your new article:

• Update your online CV and website to include a complete citation to the article.
• Inform your institution that it has been published so that it may be added to any lists of publications they maintain and disseminate.
• Post a link to your article's DOI on your blog, Facebook page, or Twitter feed.
• Share papers with the SPIE LinkedIn group using the 'share' button located on SPIE Digital Library article pages.
• Include the article in suggested reading for any of your courses for which it is relevant.
• If your institution does not currently subscribe to this journal, please recommend it to your librarian so that you and your colleagues will have access to its valuable content.

Reprints

If authors choose to order reprints, the minimum order is 100 copies. Reprints can be ordered after publication by completing and returning the reprint order form.

How to Cite

SPIE Journals use six-digit citation identifiers (CIDs) in place of traditional page numbering. This allows an issue to build online one article at a time, while retaining the ability to segment tables of contents by article type or subject area. An example of the correct citation format for an Optical Engineering article is:

A. Smith and B. Jones, "Paper title," Opt. Eng. 44(2), 023407 (2005).

In this fictitious example, the article by Smith and Jones was published in Optical Engineering in Issue 2 of Volume 44, as the seventh article published under section category 34.

In the full-text PDF file available online and in the printed article, the CID appears on each printed page. Appended at the end of the CID is a hyphen followed by a consecutive page number. For the sample article above, the printed pages would carry this page numbering: 023407-1, 023407-2, 023407-3, etc. The hyphen and additional digits should not be used when citing or searching for an article.

Article Sharing

For details about publication licenses and the associated rights to share published articles, see the SPIE policies on article-sharing.
