The United States Air Force has a pressing need for new methods of hyperspectral imaging. All current hyperspectral imaging technologies require long exposure times, since each involves filtering the available light, either spatially or according to color. We consider a recently proposed method for hypserspectral imaging that promises shorter exposure : David J. Cooke. Stokes imaging spectropolarimeters are versatile instruments to acquire Stokes-vector spectral signatures in a variety of scenes 1,2,3,4,5,6, combines the abilities of an imaging spectrometer and imaging polarimeter to provide a full four-dimensional (two spatial, one spectral, one polarization) by:
