Hyperspectral imaging




A new approach to hyperspectral imaging was developed based on Fourier transform spectroscopy, where the interference is performed by wavefront division rather than amplitude division. A variable phase delay between two parts of the wavefront emanating from each point of an object is created by a spatial light modulator (SLM) to obtain variable interference patterns. The SLM is placed in the exit pupil of an imaging system, thus enabling conversion of a general imaging optical system into an imaging hyperspectral optical system.
