Claim 9:
10. A computer implemented method for hyperspectral imaging, comprising:
receiving an event stream of events from an event camera,
wherein the event camera is coupled to an interferometer, and the event camera receives light output from the interferometer and generates the event stream comprising event data that corresponds to the light output,
wherein the events in the event stream indicate a pixel that detected an event, a time of the event, and a polarity of change in brightness detected by the pixel;
generating spectral data for the events in the event stream using a demodulation and frequency transform to convert temporospatial aggregates of events in the event stream to frequency domain data that corresponds to an optical spectrum; and
generating a hyperspectral image using the spectral data to reconstruct an input scene in a spectral range.
