Abstract

An imaging system includes a transmissive diffraction mask (TDM), a pixel array, and a processor. The TDM includes a first and a second diffraction grating configured to diffract light received from a scene to generate first diffracted light encoding information about an angle of incidence (AOI) of the received light and second diffracted light encoding information about the AOI and a state of polarization (SOP) of the received light, respectively. The pixel array includes a first and a second set of pixels configured to detect the first and second diffracted light and generate therefrom a corresponding first and second set of pixel responses, respectively. The processor is configured to determine, from the first set of pixel responses, AOI data conveying the AOI of the received light, and determine, from the second set of pixel responses and the AOI data, polarization data conveying the SOP of the received light.
