More Information
Summary:An optical sensor, optical system, and proximity sensor are disclosed. An illustrative proximity sensor is disclosed to include a light source, a photodetector including a photo-sensitive area that receives incident light and converts the received incident light into an electrical signal, and a plurality of polarization layers stacked on the photodetector that limit light from becoming received incident light for the photo-sensitive area to light traveling toward the photodetector along a predetermined path.
