Abstract	In order to establish mobile robot operations and to realize survey and inspection tasks, robust and precise measurements of the geometry of the 3-D environment is a required basic sensor technology. For visual inspection, surface classification, and documentation purposes, however additional information concerning reflectance of measured objects is necessary. High-speed acquisition of both geometric and visual information is achieved by the described active laser radar developed at Zoller+Frohlich (Z+F). In contrast to other range sensing devices, the Z+F system is designed for high-speed and high-performance operation in real indoor and outdoor environments, emitting a minimum of near-infrared laser energy. It integrates a single-point laser measurement system and a mechanical deflection system for 3D environmental measurements. Experimental results are reported from surface inspections in tunnels, the generation of 3D CAD models of a work cell in an automotive manufacturing plant and the modeling of free form surfaces such as historic sculptures.
