Abstract
In one example, an apparatus comprises a plurality of sub-pixels arranged sideway, a shared optical element positioned over the plurality of sub-pixels, the shared optical element being configured to direct light originating from a same location in a scene to each sub-pixel in the plurality of sub-pixels; one or more polarizers positioned between the shared optical element and one or more first sub-pixels of the plurality of sub-pixels and configured to selectively pass one or more components of the light having one or more pre-determined polarization states, to enable the photodiodes of each of the one or more first sub-pixels to generate signals based on intensities of the one or more components; and one or more processors configured to generate polarimetric measurements of the received light based on signals obtained from the photodiodes of the one or more first sub-pixels and polarization properties of the one or more polarizers.
