3.5 Operating principle of the LMS
The LMS is an electro-optical laser measurement system that electro-sensitively scans the
perimeter of its surroundings in a plane with the aid of laser beams. The LMS measures its
surroundings in two-dimensional polar coordinates. If a laser beam is incident on an object,
the position is determined in the form of distance and direction.
Fig. 3: Measuring principle of the LMS
Scanning takes place in a sector of 190°. The scanning range of the LMS is maximum 65 m
(213.25 ft) on light, natural surfaces with an object remission > 100% (e.g. a white house
wall).
