A Photoelectric Sensor consists primarily of an Emitter for emitting light and a Receiver for receiving light. When emitted light is interrupted or reflected by the sensing object, it changes the amount of light that ...
WebDec 1, 2000 · For our purposes, photodetectors include any device for registering photons with frequencies above that of radio waves—from far infrared on up to gamma rays. In this article we survey the main types of applications that use photodetectors. Broadly speaking, these applications fall into two general groupings—communications and remote sensing.
