Definitions for "Photodiode"
A two-electrode, radiation-sensitive junction formed in a semiconductor material in which the reverse current varies with illumination. Photodiodes are used for the detection of optical power and the conversion of optical power to electrical power.
Light detector in a fiber optic signal transport system that generates an electric current in proportion to the intensity of the light falling on it.
It is a photosensitive semiconductor diode.
A single photoelectric sensor element, either used stand-alone or a pixel site, part of a larger sensor array.
