Imaging Fourier spectrometer in visible domain: design concept.

A prototype of an imaging Fourier spectrometer, with corner-cube reflectors in the Michelson interferometer, is developed for visible and near-infrared domains. The use of corner-cube reflectors enables stability of operation, while imaging capability makes wide field of view and, consequently, increases input optical signal. In the imaging mode of operation, the optical signal is recorded by a high-speed camera, enabling spectral measurements in each pixel of the image.
