Laser Phase Shift
The SLS Laser Distance Measurement Sensor is designed for mobile and stationary distance measurement in an industrial environment. The SLS works based on comparative phase measurement. To achieve this, it emits visible laser beams in different frequencies. The target being measured returns diffusely reflected light that is subsequently compared with a reference signal. Finally, a microprocessor uses the recorded phase shift to calculate a required distance with mm accuracy. The sensor SLS distinguishes itself through high precision as well as independence of the surface of the measured object. The red, well visible laser beam, allows a simple alignment.
