Abstract:
1. A hyperspectral imaging system having an optical path, said system comprising: an illumination source configured to output a light beam, said light beam illuminating a target; a dispersing element arranged in said optical path and configured to separate said light beam into a plurality of wavelengths; a spatial light modulator configured to tune said plurality of wavelengths into a spectrum; an optical device comprising a detector and configured to collect said spectrum reflected from said target and arranged in said optical path; and, a processor operatively connected to and configured to control at least one of: said illumination source; said dispersing element; said spatial light modulator; said optical device; and, said detector, said processor further configured to output a hyperspectral image of said target, wherein said dispersing element is arranged between said illumination source and said spatial light modulator, said spatial light modulator is arranged to transmit said spectrum to said target and said optical device is arranged in said optical path after said target, wherein said detector comprises a plurality of pixels and said processor further comprises a deconvolution algorithm configured to normalize said spectrum at each of said plurality of pixels prior to processing said hyperspectral image.
