The working principle of the laser ranging sensor is that the laser diode is aimed at the target to emit laser pulses. The laser is reflected by the target and scattered in all directions. Part of the scattered light returns to the sensor receiver and is imaged on the avalanche photodiode after being received by the optical system. Avalanche photodiode is an optical sensor with internal amplification function, so it can detect extremely weak optical signals. By recording and processing the time from sending optical pulses to returning and receiving, the target distance can be determined. In addition, the laser ranging sensor is powerful and durable, specially designed for the industrial measurement market. Laser ranging sensor has many excellent properties, and it is the most advanced and economical online position detection system with amazing test accuracy and high stability. Because the distance is accurately calculated by emitting a laser beam to the target object and using the reflected beam, a long detection distance can be achieved without adding a reflecting target, and the size area of the target object is much smaller than that required by ultrasonic waves, which makes it possible to detect the position of small-sized objects from a distance now.
