Abstract:
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 Fourier transform to the sum of intensities of the first modulated signal and the second modulated signal at the plurality of optical frequencies and obtain an intensity coefficient of electromagnetic radiation incident each of the first location and the second location for each of the plurality of optical frequencies.
