您好！光電旋轉編碼器在英文中通常被稱(chēng)為Optical Rotary Encoder。

An optical rotary encoder is a device used to convert the angular position or motion of an object into an electrical signal. It is primarily used to measure the rotation of a shaft or wheel and is widely used in various industries and applications such as robotics, automation, CNC machines, motion control systems, and more.

The optical rotary encoder consists of a light source, a rotating disk or wheel with evenly spaced slots or marks, and a photodetector. As the disk or wheel rotates, the light passing through the slots or marks on the disk is interrupted and detected by the photodetector, generating electrical pulses. These pulses are then processed to determine the position, speed, or direction of rotation.

The advantages of optical rotary encoders include high resolution, high accuracy, and fast response time. They provide precise feedback and allow for precise control and positioning of the object being measured. Additionally, they have a long operating life, low friction, and are not prone to mechanical wear and tear.

Optical rotary encoders are available in different types, such as incremental encoders and absolute encoders. Incremental encoders provide relative position information and require a reference point to calculate the absolute position. Absolute encoders, on the other hand, provide absolute position information without the need for a reference point.

In conclusion, the Optical Rotary Encoder (光電旋轉編碼器) plays a crucial role in measuring and controlling angular position or motion. Its accurate and reliable performance makes it an essential component in various industries and applications.
