Laser displacement sensor

The commonly used high-precision laser displacement sensors are mainly made using the principle of laser triangulation. The laser emitter shoots the laser towards the surface of the measured object, and the linear camera inside the displacement sensor receives the reflected laser from the object. The distance between the sensor and the measured object is calculated through an internal digital signal processor. The measurement range is 0-2m; The measurement accuracy reaches 0.2 μ m/m; The linearity reaches 0.1%, with advantages such as non-contact, simple structure, anti-interference, strong adaptability, and fast speed; The disadvantages are high measurement costs and high environmental requirements.
