Distance Measurement for Reflecting Surfaces with Universal Laser Sensor

Distance Measurement for Reflecting Surfaces

Plastics, mirrored glass, or metals have highly reflective surfaces and require special laser sensors to measure displacement and distance. Displacement and distance measurements on strongly reflecting surfaces challenge conventional, diffuse reflection laser sensors. 

Laser sensors such as the Micro-Epsilon optoNCDT 1750DR provide a real-time surface compensation feature that controls exposure time that produces stable signals. This type of laser sensor operates on the principle of direct reflection, aligned so that the angle of incidence is equal to the angle of reflection. Proprietary algorithms compensate for the back-scattered, high-intensity light—all of this in a compact design, including an integrated controller (no external control unit is required).

Mounting and wiring are easy. A mounting template enables the user to align the sensor correctly. The laser class 1 rating on which the optoNCDT 1750DR operates is another advantage. Additional safety precautions are not necessary since the emitted laser power does not exceed 390 µW. Users have the choice of an intuitive web interface which can operate the laser sensor from a browser.
