Claim:
1. A method of obtaining a hyperspectral image of a target comprising the steps of: generating a light beam; dispersing said light beam with a dispersing element; separating said dispersed light beam into a first complex spectrum using a spatial light modulator; illuminating said target with said first complex spectrum, wherein said first complex spectrum subsequently reflects off of said target as a first reflected light beam; collecting said first reflected light beam; directing said collected first reflected light beam to a detector to capture a first spectral image data; separating said dispersed light beam into a second complex spectrum using said spatial light modulator; illuminating said target with said second complex spectrum, wherein said second complex spectrum subsequently reflects off of said target as a second reflected light beam; collecting said second reflected light beam; directing said collected second reflected light beam to said detector to capture a second spectral image data; and, forming said hyperspectral image from said first and second spectral image data, wherein said detector comprises: wherein said step of forming a hyperspectral image comprises the steps of: wherein the step of calculating a spectra ratio for each of said plurality of pixels comprises: wherein the step of normalizing said filtered data set to create a normalized data set comprises:
