1. A polarization imaging system, comprising:
a first lens positioned at an entrance of the polarization imaging system and covering a full field of view of the polarization imaging system to receive light from one or more objects; and
a spectral-polarization filter positioned at an aperture stop of the polarization imaging system to filter the received light, the spectral-polarization filter comprising an array of multiple spectral filters and an array of multiple polarizers that are positioned in cascade to modify both spectral content and polarization of the light that enters the spectral-polarization filter; wherein
the light that exits the spectral-polarization filter is directed to a sensor positioned to detect filtered light from the spectral-polarization filter at an image plane of the polarization imaging system.
