Claim 0:
1. A system for hyperspectral imaging, comprising:
an interferometer coupled to an event camera, wherein light output from the interferometer is provided to the event camera which generates an event stream of events that correspond to the light output,
wherein the event camera has a pixel array comprising a plurality of pixels configured to independently detect an event representative of a change in brightness, and to independently generate an indication of the event in response to detecting the event;
at least one processor;
a memory device including instructions that, when executed by the at least one processor, cause the system to:
receive the event stream from the event camera, wherein an event in the event stream indicates a pixel that detected an event, a time of the event, and a change in brightness detected by the pixel;
generate 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
generate a hyperspectral image using the spectral data to reconstruct an input scene in a spectral range.
