Classification: CPC G | IPC G

Claim 17:
18. A non-transitory machine readable storage medium including instructions embodied thereon, wherein the instructions, when executed by at least one processor:
receive 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 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 video stream of hyperspectral image frames using the spectral data to reconstruct an input scene in a spectral range.
