    Abstract: The present disclosure relates to an optical sensor system and an apparatus. The optical sensor system comprises a photodetector. The photodetector comprises a plurality of photosensitive elements and a photosensitive region disposed about and distinct from the photosensitive elements. The optical sensor system further comprises an optical system configured to image optical energy on the photodetector. The optical sensor system further comprises an electrical circuitry coupled to each of the photosensitive elements and to the photosensitive region disposed about the plurality of photosensitive elements. The apparatus comprises a detector array having three detector elements each detector element comprising a photosensitive material. The apparatus further comprises electrical circuitry coupled to each of the three detector elements.

    Abstract: In accordance with one embodiment of the present disclosure, a system may include a polarizing beamsplitter for splitting one or more unpolarized rays received from an illumination source into a first polarized component and a second polarized component, the first polarized component and the second polarized component having orthogonal polarizations to each other. The system may also include a half-wave plate for rotating the second polarized component to the same polarization as the first polarized component. The system may further include a lens group for passing the first polarized component to a target plane as a first polarized ray, and further for separately passing the second polarized component to the target plane as a second polarized ray.
