photodetector

(foh-toh-di-tek -ter) Any electronic device designed to respond to, i.e. detect, photons of light or other radiation. Examples include the photomultiplier and CCD.

photodetector

[¦fōd·ō·di′tek·tər]
(electronics)
A detector that responds to radiant energy; examples include photoconductive cells, photodiodes, photoresistors, photoswitches, phototransistors, phototubes, and photovoltaic cells. Also known as light-sensitive cell; light-sensitive detector; light sensor photodevice; photodevice; photoelectric detector; photosensor.

photodetector

A device that senses light. It uses the principle of photoconductivity, which is exhibited in certain materials that change their electrical conductivity when exposed to light. See photoelectric, photocell and photodiode.
