Detection system for optical coherence tomography: Czerny-Turner spectrometer

Research methods based on spectral analysis have powerful impact on development in many field of science. Signal spectrum can be a source of useful and important data. It enables to obtain information about physical and chemical properties of tested materials. This paper has been devoted to describe optical design for high resolution spectrometer, which is significant element of optical coherence tomography (OCT) systems. Designed spectrometer is working in visible range (450-830 nm). Czerny-Turner configuration enables to correcting astigmatism and coma aberration over full bandwidth. Moreover, spectrometer has uncomplicated construction. Merely, two mirrors and diffraction gratings allows to design low – cost spectrometer with satisfying optical properties. Spectrum detection has been realized using CMOS line scan sensors with 6144 pixels. It provides high speed and resolution of the system.
