DLR Laser-range Scanner (2000)
The DLR Laser Range Scanner is a device for the exploration of three-dimensional environments. It uses the principle of laser triangulation, as shown in Figure 1. A laser beam is send from a source and will be dispersed diffusely on the scanned object's surface. Some of the reflected rays strike a lens which focuses the light onto a sensitive area of a position sensitive detector (PSD).
