Abstract

A spectral-domain optical coherence tomography system using a cross-dispersed spectrometer is disclosed. The interfered optical signal is dispersed by a grating into several orders of diffraction, and these orders of diffraction are separated by an additional dispersive optical element. The spectral interferogram is recorded by a set of linear detector arrays, or by a two-dimensional detector array.
