Photoelectric transducer
0399201-160
[DEFINITION]
A transducer that generates an electric output corresponding to the
incident light.
[DESCRIPTION]
Photoelectric transducers are divided into two groups according to
their applications: 1) a photo-detector that handles light signals, and 2) a photovoltaic power
system such as a solar battery that responds to light energy. In the former case, sensitivity and
response speed are important, while in the latter case, energy conversion efficiency is important.
Classified by their operating principles, photoelectric transducers can be divided into a
photovoltaic type, typified by photodiodes and solar batteries, and a photo-conductive type,
typified by photo-conductive cells and image pick-up tubes.
