Crossed dispersion spectrometer in the spectral domain optical coherence tomography system

摘要

Spectral domain optical coherence tomography system using a cross-dispersion spectrometer is disclosed. Optical signal interference is distributed in a plurality of diffraction orders by a diffraction grating, diffraction orders of which are separated by a dispersive optical element added. Spectral interferogram is recorded by the two-dimensional detector array, or by a linear detector array of a pair.
