1. A system for hyperspectral imaging, comprising:
a spatial light modulator having a plurality of pixels, including a first pixel at a first location adapted to encode electromagnetic radiation incident the first location into a first modulated signal having a first modulation frequency, and at least a second pixel at a second location adapted to encode electromagnetic radiation incident the second location into a second modulated signal having a second modulation frequency, wherein the first modulation frequency is different from the second modulation frequency; an optical demultiplexer; one or more optical elements arranged to couple at least the first modulated signal and the second modulated signal into the demultiplexer, the demultiplexer adapted to measure a sum of intensities of at least the first modulated signal and the second modulated signal at a plurality of optical frequencies; and one or more processors, operatively coupled to the demultiplexer, configured to apply a transform to the sum and obtain an intensity of electromagnetic radiation incident each of the first location and the second location for each of the plurality of optical frequencies. |
