Abstract:
A polarization imager is provided that includes a plurality of CMOS photodetectors and a plurality of polarization filters. Each of the plurality of CMOS photodetectors has a photodiode that is configured to operate in forward bias mode. Further, each of the plurality of polarization filters is monolithically integrated with a corresponding one of the plurality of CMOS photodetectors. Each of the plurality of photodiodes exhibits a logarithmic response to a flux of incident photons. The polarization imager achieves a dynamic range of at least 100 decibels with a signal-to-noise ratio of at least 60 decibels.
