After the studying of many theoretical courses, it’s important and urgent for the students from specialty of optoelectronic information science and engineering to cultivate their comprehensive ability of photoelectricity. We set up a comprehensive practice course named “Integrated Design of Optoelectronic Information System” (IDOIS) for the purpose that students can integrate their knowledge of optics, electronics and computer programming to design, install and debug an optoelectronic system with independent functions. Eight years of practice shows that this practice course can train students' ability of analysis, design/development and debugging of photoelectric system, improve their ability in document retrieval, design proposal and summary report writing, teamwork, innovation consciousness and skill.



Optoelectronic information industry is the most attractive sunrise and the high-tech leading industry in the 21st century[1,2]. To meet the needs of social development, Beijing Information Science and Technology University established the undergraduate program of “optical information science and technology” in 2004, which directly serves the optoelectronic information industry. This program is based on optics and electronics, and combines with computer science, precision machinery and other disciplines, focusing on the design and implementation of optoelectronic systems. In 2005 it was identified as the Beijing brand building program, in 2007 become the school key construction professional and in 2013 its name was changed to be “Optoelectronic information science and engineering”.

Many practice and innovation courses are set up, as shown in Fig 1, in addition to course experiments, a three level independent practice system from the fundamental part to the unit design and then the system design is constructed, with all kinds of innovative practice, strengthen the cultivation of students' practical ability and innovation consciousness.

As an important comprehensive practice activities courses [3,4], Integrated Design of Optoelectronic Information System (IDOIS) is an important part of the three-tier practice system, and the professional compulsory practical courses of the Optoelectronic information science and engineering. On the basis of some prerequisite courses, such as photoelectric detection technology and system, laser principle and application, digital image processing and application and optical system design, combined with the characteristics of optoelectronic engineering, from IDOIS the students can learn and realize an integrated application system of photoelectricity to Solve complex engineering problems.

This course is not only the support for the following graduation design, but also the support for the work after graduation.

On the basis of the completion of theoretical course study and other practical courses, through the study of this course, students can apply the knowledge of optical, mechanical and computer programming, and carry out the process of designing, installing and debugging the optoelectronic information system with independent function. Focus is put on improving students’ ability of combining theory with practice and innovation, cultivating comprehensive knowledge and realization methods of product design, process and test technology and other aspects. Through this course, the students will exercise their ability of analysis, design / development and debugging the integrated optoelectronics and electromechanical system, improve their comprehensive quality and ability of scientific information retrieval, conceptual design, summary report writing, teamwork, Innovation consciousness and innovation ability, and personal presentation. So that lay a solid foundation for future related work.

Means for achieving the course aims

  • 1. Grouping and topic determination: The students are divided into several 3-4 member groups. Each group determines the topic and content of the course by considering the advices from instructors according to preferences.

  • 2. Schematic formulation: Under the guidance provided by instructors, the students are supposed to analyze the principle, build model, picture out block diagrams, derive the specifications of various modules, figure out the Input/Output relationships, and work out the realizing routines. In this section, the students are specifically supposed to be capable of drawing correctly circuit diagrams and light path diagrams, calculating characteristic parameters, and providing budgets.

  • 3. Opening presentation: The schematic design and budget will be evaluated and graded.

  • 4. Operations in Labs: Students will then implement their task in the labs under guidance. The behavior of each students in the labs including attendance, recordings, and costs will be graded.

  • 5. Teamwork: Within the groups, toward a common goal and with clear job divisions, each member undertakes a partial responsibility and cooperates with other members to complete the project task.

  • 6. Intermediate inspection: The rate of progress will be graded for each group.

  • 7. Final check: The integrated electronic system object, experimental data and results developed by each group will be checked and graded.

  • 8. Written report: Each group is supposed to hand in a written report. The report will be reviewed in terms of format and graded.

  • 9. Final presentation: Students are supposed to give a final presentation.

We started IDOIS in 2009. Over the past eight years, we have continued to sum up our experience, update our design content, add new projects, and eliminate obsolete or unsuitable projects. The vast majority of students can seriously complete the subject requirements. The physical acceptance results show that each group can complete the basic functional requirements and technical requirements. Scores are given according to the comprehensive performance of each student. Some outstanding students have the ability to carry out independent scientific research. The student’s harvest is great, mainly in the professional knowledge, theory and practical ability.
