QuellTech laser-scanners make use of the triangulation principle to detect the two-dimensional profile of surfaces. By means of particular optical components, a point-shaped laser beam is expanded to a line and projected to the object of interest. The diffuse light of the reflected laser line is captured by an objective at a certain angle and then directed to a two-dimensional receiver chip.
