Abstract

A method and apparatus for analyzing an optical image of a scene to determine the spectral intensity of each pixel thereof, by: collecting incident light from the scene; scanning the incident light; passing the scanned light through an interferometer which outputs modulated light corresponding to a predetermined set of linear combinations of the spectral intensity of the light emitted from each pixel; focusing the light outputted from the interferometer on a detector array; and processing the output of the detector array to determine the spectral intensity of each pixel thereof.
