Abstract

The quality of the spectrometer affects the sensitivity fall-off, axial resolution, and depth scan range, therefore overall performance of the spectral domain optical coherence tomography (SD-OCT) imaging. Chromatic aberration, optical resolution, and detector array resolution are the key design consideration for high-quality OCT spectrometer. Traditionally refractive optics spectrometer is used in SD-OCT. In the present work, the optical design of the reflective optics spectrometer and of the refractive optics spectrometers is reported for high-speed line field optical coherence tomography imaging. The performance of the spectrometers was compared by using the ZEMAX optical design software. The ZEMAX optical modeling analysis shows that the reflective optics spectrometer provides better performance by comparison with the refractive optics spectrometer.
