Abstract
An optical sensor, optical system, and proximity sensor are disclosed. An illustrative proximity sensor is disclosed to include a light source and a photodetector including a photo-sensitive area that receives incident light and converts the received incident light into an electrical signal. The light source and photodetector are positioned diagonally relative to one another, thereby enabling the devices to be positioned closer together on a body or substrate.
