Laser triangulation: contactless sensors of position and displacement.
optoNCDT laser sensors uses laser triangulation for measurement. Triangulation means distance measurement by angle calculation. In measurement technology, a Sensor projects a laser spot onto the Measurement object. The reflected light falls incident onto a receiving element at a certain angle depending on the distance. From the position of the light spot on the Receiver element and the distance from the sender to the Receiver element, the distance to the Measurement object is calculated in the Sensor.
Optical displacement sensors can execute distant measurement with very small measuring spot. Altmost all modes are equipped with high resolution CCD matrix or CMOS-line andDSP (digital signal processing).
