Optical Sensors
A photoelectric sensor, or photoeye, is a device
used to detect the distance, absence, or presence of an object by using a
light transmitter (often infrared) and a photoelectric receiver. They
are used extensively in industrial manufacturing. There are three
functional types: opposed (a.k.a. through-beam), retroreflective, and
proximity-sensing.
