The laser sensor utilizes the high direction, high monochrome, and high brightness of the laser to realize non-contact remote measurement. Laser sensors are often used to measure physical quantities such as length, distance, vibration, speed, and direction. They can also be used for flaw detection and air pollutant monitoring. In short, the application of laser sensors is becoming more and more extensive. The following introduces the types of laser sensors and their main principles and applications, hoping to help everyone.

The laser displacement sensor can realize non-contact long-distance measurement by utilizing the characteristics of high directivity, high monochromaticity and high brightness of the laser. Laser displacement sensor (magnetostrictive displacement sensor) is a new type of measuring instrument made of these advantages of laser. Its appearance greatly improves the accuracy and reliability of displacement measurement, and also provides effective non-contact displacement measurement. measurement method.
