The scanning is performed by the Flying Spot Principle using a single spot instead of a laser line.
The intensity of the laser light is furthermore continuously adapted by feed back to the optimal intensity for the surface of the application.
The measurement is performed by oscillating the triangulation plane over an angel. The angel can be specified to a maximum of 50°. A fine collimated or focused laser beam is diffusely reflected from the surface of almost any kind of object, and a CCD-camera records the image through an objective.
