Digital optical encoder a digital optical encoder is a device that converts motion into a sequence of digital pulses. By counting a single bit or by decoding a set of bits, the pulses can be converted to relative or absolute position measurements. Encoders have both linear and rotary configurations, but the most common type is rotary, Gray code
Fiber Optic Detector detectors perform the opposite function of light emitters. They convert optical signals back into electrical impulses that are used by the receiving end of the fiber optic data, pdf file

Opto sensors opto sensor consists of a light emitting element which transforms an electrical signal to an optical signal, and a light receiving element which transforms the optical signal to an electrical signal. Both of these elements are housed in one package, making the opto sensor essentially a non- contact switch
Photo-conductive Cell Photocells are thin film devices made by depositing a layer of a photoconductive material on a ceramic substrate. Metal contacts are evaporated over the surface of the photoconductor and external electrical connection is made to these contacts, pdf file

Photocells photoresistors (photocells) are simply variable resistors in many ways similar to potentiometers, except that the resistance change in light level rather than by turning a knob. Photoresistors can be used as light sensors, which can enable robot behaviors such as hiding in the dark, moving toward a beacon, etc.
