The Process Of Position Sensing

Position sensing is the process by which a position sensing detector or detectors and other equipment are used to accurately measure and determine an exact line, point or position, often across long distances. This process is most commonly used in the manufacturing and building of aircraft, ships and large trucks as well as many other applications.

Position Sensing Detectors or “PSD’s”, are made of silicon photodiodes that provide an analog output of the position of a light spot on the detector's active area. This output from the PSD simultaneously monitors position and light intensity and gives a precise measurement. The PSD is a continuous analog position sensor and its advantages are: outstanding position linearity, high analog resolution, fast response time, and simple operating circuits.

We manufacture the OT-301, OT-302D, OT-301SL, OT-301DL, and PSM modules. We are also the sole distributor in the USA for SiTek Electro Optics for their 1L and 2L series detectors.
