Photoelectric rotary encoder, which is also called photoelectric angel position sensor, is a kind of digital angle measuring device combining optics, mechanics and electronics. Owing to its simple structure, high resolution, and high accuracy, the photoelectric rotary encoders have been used generally in the systems of fine angel position measurement, digital control and digital display. The domestic and foreign development in photoelectric rotary encoders are mainly introduced, and its working principle, developing history are described briefly as well. Some key technologies of photoelectric encoders and its developing trends are summarized at last.
