In the production, the main applications are in dimension control and automated assembly. Dimensions of brakes, clutches, axles and whole bodies are checked. In the assembly sector contours have to be recorded if possible along a measuring line and not only at points.

Here, laser scanners are used in which the measuring beam is deflected by a system of mirrors and systems with CCD matrix detectors (light intersection sensors) in which a measuring line is generated by optical expansion. Such systems are used mainly in the robot assembly of doors and wind- screens. Their measuring line offers the advantage of being able to measure gaps from other body parts exactly. Sensors with a special protective flap are available for position the welding heads of robots.
