Principle: Laser Line Triangulation

QuellTech Q4 laser scanner 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.

On the basis of distances and angles known, a precise calibrated height value (z) is calculated for each pixel in the x level (laser line), resulting in a precise profile in the x-z plane of the sample. If the scanner is guided over the sample (y axis), a series of profiles is created forming a three-dimensional point cloud in space. This point cloud can be subjected by dimensional control carried out by the software.
