POSITION SENSITIVE DETECTOR Position Sensitive Detector (PSD) is an optical position sensor (OPS), that can measure a position of a light spot in one or two-dimensions on a sensor surface.The PSD is a precision semiconductor optical sensor which produces output currents related to the “centre of mass” of light incident on the surface of the device.

DUAL AXIS PSD This particular PSD is a five terminal device bounded by four collection surfaces; one terminal is connected to each collection surface and one provides a common return. Photocurrent is generated by light which falls on the active area of the PSD will be collected by these four perimeter electrodes .
