The Triangulation Technique is an Ancient Yet Very Accurate Way of Measuring Distance.
Our specialty is measurement of distance, thickness, width, difference, level, height and shape. Performed on almost all kind of surface such as asphalt, cardboard, fiber, foam, food, glass, granulate, liquid, metal, paper, plastic, powder, rubber, steel, stone and wood.
In a high quality laser sensor, a CCD-camera is used to record the emitted laser light. The way to illustrate this measuring principle is to follow a ray tracing from the laser optics to the target, and back to the CCD-camera.
For laser triangulation sensors of the highest quality, there is naturally more to it than the basic principle. To obtain the absolutely best measuring quality, advanced and powerful digital electronics must be used all the way from the recording CCD-camera to the output signals.
