Rotational Speed Sensor

Rotational speed sensor, also known as remote optical laser sensor, laser photoelectric speed sensor, is a sensor that uses the laser photoelectric effect to measure the speed of an object. The main measurement principle is to determine the rotational speed of an object by utilizing the characteristics of the reflected laser beam on the surface of the object. When the laser beam strikes the surface of an object, it will be reflected back to the sensor. The photosensitive element in the sensor can convert the reflected laser signal into electrical signals, and by processing these electrical signals, the rotational speed of the object can be determined.
