Abstract
Methods, apparatus and systems that relate to a low-cost reconfigurable polarimetric imaging are described. One example polarization imaging system includes a lens positioned to receive light reflected from one or more objects, and a spectral-polarization filter positioned at an aperture plane of the lens to filter the light received by the lens. The polarization imaging system can further include a sensor positioned to detect the filtered light from the spectral-polarization filter to form a polarization image of the one or more objects. The spectral-polarization filter comprises a first array of multiple spectral filters and a second array of multiple polarizers.
