SignificanceRaman spectroscopy has been used as a powerful tool for chemical analysis, enabling the noninvasive acquisition of molecular fingerprints from various samples. Raman spectroscopy has proven to be valuable in numerous fields, including pharmaceutical, materials science, and biomedicine. Active research and development efforts are currently underway to bring this analytical instrument into the field, enabling in situ Raman measurements for a wider range of applications. Dispersive Raman spectroscopy using a fixed, narrowband source is a common method for acquiring Raman spectra. However, dispersive Raman spectroscopy requires a bulky spectrometer, which limits its field applicability. Therefore, there has been a tremendous need to develop a portable and sensitive Raman system.AimWe developed a compact swept-source Raman (SS-Raman) spectroscopy system and proposed a signal processing method to mitigate hardware limitations. We demonstrated the capabilities of the SS-Raman spectroscopy by acquiring Raman spectra from both chemical and biological samples. These spectra were then compared with Raman spectra obtained using a conventional dispersive Raman spectroscopy system.ApproachThe SS-Raman spectroscopy system used a wavelength-swept source laser (822 to 842 nm), a bandpass filter with a bandwidth of 1.5 nm, and a low-noise silicon photoreceiver. Raman spectra were acquired from various chemical samples, including phenylalanine, hydroxyapatite, glucose, and acetaminophen. A comparative analysis with the conventional dispersive Raman spectroscopy was conducted by calculating the correlation coefficients between the spectra from the SS-Raman spectroscopy and those from the conventional system. Furthermore, Raman mapping was obtained from cross-sections of swine tissue, demonstrating the applicability of the SS-Raman spectroscopy in biological samples.ResultsWe developed a compact SS-Raman system and validated its performance by acquiring Raman spectra from both chemical and biological materials. Our straightforward signal processing method enhanced the quality of the Raman spectra without incurring high costs. Raman spectra in the range of 900 to 1200 cm−1 were observed for phenylalanine, hydroxyapatite, glucose, and acetaminophen. The results were validated with correlation coefficients of 0.88, 0.84, 0.87, and 0.73, respectively, compared with those obtained from dispersive Raman spectroscopy. Furthermore, we performed scans across the cross-section of swine tissue to generate a biological tissue mapping plot, providing information about the composition of swine tissue.ConclusionsWe demonstrate the capabilities of the proposed compact SS-Raman spectroscopy system by obtaining Raman spectra of chemical and biological materials, utilizing straightforward signal processing. We anticipate that the SS-Raman spectroscopy will be utilized in various fields, including biomedical and chemical applications.

In coherent imaging systems, parasitic fringes and concentric patterns could commonly be found due to the unwanted multiple reflections [1]. One fundamental solution for the coherent noise is to use a temporally incoherent light source. However, maintaining the full-field interference fringe contrast using temporally incoherent light is not straightforward for interferometric imaging techniques such as quantitative phase imaging (QPI). Fortunately, several brilliant incoherent QPI techniques have been realized for wide-field imaging mainly through the common-path interferometer geometries [2-4]. However, it has been more difficult to implement incoherent-light-based optical diffraction tomography (ODT) due to the additional angle-scanning illumination unit that induces severe decoherence over the camera field-of-view [5]. Here, we suggest a temporally low-coherence optical diffraction tomography by angle-scanning broadband illumination based on general Mach-Zehnder interferometric geometry. We have designed an angle-scanning unit composed of two digital micromirror devices (DMDs) to maintain interference fringe contrast across the whole field of view during the angle-scanning sequence. Further, we have developed the theoretical framework for ODT reconstruction using incoherent light. In the light of our recent developments, we will discuss the theoretical and practical constraints, and suggest the best degree of incoherency for incoherent ODT. We will also demonstrate the incoherent optical diffraction tomography of plastic microspheres, human blood cells and rat pheochromocytoma cells. References 1. I. Choi, K. Lee, and Y.

Quantitative phase measurements at multiple wavelengths has created an opportunity for exploring new avenues in phase microscopy such as enhancing imaging-depth (1), measuring hemoglobin concentrations in erythrocytes (2), and more recently in tomographic mapping of the refractive index of live cells (3). To this end, quantitative phase imaging has been demonstrated both at few selected spectral points as well as with high spectral resolution (4,5). However, most of these developed techniques compromise imaging speed, field of view, or the spectral resolution to perform interferometric measurements at multiple colors. In the specific application of quantitative phase in studying blood diseases and red blood cells, current techniques lack the required sensitivity to quantify biological properties of interest at individual cell level. Recently, we have set out to develop a stable quantitative interferometric microscope allowing for measurements of such properties for red cells without compromising field of view or speed of the measurements. The feasibility of the approach will be initially demonstrated in measuring dispersion curves of known solutions, followed by measuring biological properties of red cells in sickle cell anemia.

We developed a 3-D image cytometer based on two-photon scanning microscopy. The system keeps the inherent advantages from two-photon scanning microscopy: (1) The ability of imaging thick tissue samples up to a few hundred micrometers, (2) The ability to study tissue structures with subcellular resolution, (3) The ability to monitor tissue biochemistry and metabolism, and (4) The reduction of specimen photobleaching and photodamage. Therefore, 3-D image cytometer has the ability to characterize multiple cell layer specimens, in contrast with 2-D image cytometer where only single cell layer samples can be imaged. 3-D image cytometry increases its frame rate by adapting a polygonal mirror scanner and high-speed photomultiplier tubes. The current frame rate is 13 frames per second. High throughput rate is achieved by imaging multiple cell layer specimens in 3-D at a high frame rate. The throughput rate of this system is dependent on the choice of objective lenses, specimen properties, and the speed of computer-controlled specimen stage. It can be up to approximately 100 cells per second which is comparable with that of 2-D image cytometers. With the high throughput rate and deep tissue imaging capability, 3-D image cytometer has the potential for the detection of rare cellular events inside living, intact tissues. A promising application of this 3-D image cytometer is the study of mitotic recombination in tissues. Mitotic recombination is a mechanism for genetic change. Therefore it is one of causes for carcinogenesis. However, the study of this process is difficult because recombination event is rare and it occurs at a rate of one cell in 10⁵ cells. The new method for the study is (1) to engineer transgenic mice whose cells will express fluorescence in the presence of mitotic recombination, (2) to detect cells which have undergone mitotic recombination with 3-D image cytometry. The estimated time required to quantify spontaneous recombination rate is approximately within a few hours in the case that the mutation occurs at a rate of 1/10⁵. The ability of this 3-D image cytometer to resolve tissue structures at video rate was demonstrated in the study of ex vivo human skin dermal structure. 25 X 25 section images were taken by shifting the acquisition region with computer- controlled specimen stage. Wide area images were reconstructed by combining each image sections. The size of complete wide area images is approximately 25 mm X 25 mm. We further performed experiments to verify this cytometer's ability for population statistics measurement. We prepared cell cultures containing a mixture of cells expressing cyan and yellow fluorescent proteins. These cell cultures with mixing ratio ranging from 1/10 up to 1/10⁵ were imaged. Experimental results show that the presence of a few rare cells in large pool of the other cells can be quantitatively measured. We also imaged a punched ear specimen from a transgenic mouse which carries green fluorescent protein. The data demonstrates that this system can resolve a single green fluorescent cells in the tissue.
