Digital light processing hyperspectral imaging apparatus
First Claim
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.

Abstract
A hyperspectral imaging system having an optical path. The system including an illumination source adapted to output a light beam, the light beam illuminating a target, a dispersing element arranged in the optical path and adapted to separate the light beam into a plurality of wavelengths, a digital micromirror array adapted to tune the plurality of wavelengths into a spectrum, an optical device having a detector and adapted to collect the spectrum reflected from the target and arranged in the optical path and a processor operatively connected to and adapted to control at least one of: the illumination source; the dispersing element; the digital micromirror array; the optical device; and, the detector, the processor further adapted to output a hyperspectral image of the target. The dispersing element is arranged between the illumination source and the digital micromirror array, the digital micromirror array is arranged to transmit the spectrum to the target and the optical device is arranged in the optical path after the target.
