ABSTRACT:
An imaging system having a programmable spectral transmission function, that includes an input image plane for passing input imaging light into the imaging system; a dispersive optical system for separating the input imaging light into its corresponding spectral components, thus creating spectrally-dispersed image components along a spectrally-dispersed direction. Also included is a spatial light modulator, having a plurality of operational states, for selecting spectral components for imaging; and having a width along the spectrally-dispersed direction; a de-dispersive optical system for re-combining the selected spectral components for imaging onto a detector array; and means for scanning the input imaging light from an object of interest to generate an output area image.
