1. Introduction
A laser distance sensor is a photoelectric sensing device that uses laser as the detection light source and achieves precise measurement of the target distance based on the principle of optical ranging. It has core advantages such as high precision, high response, and non-contact measurement. By utilizing the high directivity, high monochromaticity, and high brightness characteristics of laser, it emits a laser beam to the target, receives the reflected laser signal of the target, and then converts the light signal into an electrical signal and processes it through internal algorithms to quickly output the distance value of the target. The measurement results can be directly transmitted as digital signals and are compatible with various control systems and terminal equipment.
