"WebLaser Profiling. Laser measurement systems include a CMOS camera and a laser light source. The operating principle is based on a laser beam projected on the surface of the target material under measurement. This beam or part of it is then reflected onto a detector, shifting its position in the receiver as its location varies in the object surface. " - Depth profiling of surface damage
