The advantage of the photoelectric encoder is that there is no contact wear, thus allowing high speed, high frequency response, stable and reliable, sturdy and durable, and high precision; its disadvantage is that the structure is more complicated and the price is more expensive. Photoelectric code discs have been widely used in CNC machine tools, servo motors, robots, rotary machinery, transmission machinery, instrumentation and office equipment, automatic control technology and detection and sensing technology, and the application fields are constantly expanding.

working principle
When working, the light is projected on the code disc, and the code disc rotates with the moving object. The light passing through the bright area passes through the slit and is received by the photosensitive element. The arrangement of the photosensitive element corresponds to the code track one by one. The signal output by the photosensitive element, the former is "1", the latter is "0", when the code wheel rotates in different positions, the combination of the output signal of the photosensitive element reflects a certain regular digital quantity, representing the angle of the code wheel axis displacement.

The working part of the optical encoder angular displacement measurement system is introduced.

The optical code disc is divided into three ways: binary, decimal and cyclic code according to its coding method:

Incremental and absolute encoders: According to the working principle, encoders can be divided into two categories: incremental and absolute. The incremental encoder converts the displacement into a periodic electrical signal, and then converts the electrical signal into a count pulse, and the number of pulses represents the magnitude of the displacement. Each position of the absolute encoder corresponds to a certain digital code, so its indication is only related to the starting and ending positions of the measurement, and has nothing to do with the intermediate process of the measurement.
