Abstract
A homodyne encoder encodes light sampled from an object with respective primary apertures for each spectral band. The multi-band homodyne encoder includes an optical spreader and a focusing optic. The optical spreader spreads apart the light from the respective primary apertures for each spectral band to respective secondary apertures for each spectral band. The optical spreader is arranged to spread, for each spectral band, the light from each one of the primary apertures for the spectral band to a respective one of the secondary apertures for the spectral band. The focusing optic focuses the light from the secondary apertures for all of the spectral bands into one or more composite images of the object. For each spectral band, every pairing of two of the primary apertures for the spectral band contributes distinct spatial frequencies to the composite image or images of the object.
