Measurement principle
The device is an opto-electronic LiDAR sensor that uses non-contact laser beams to
scan the outline of its surroundings. The device measures its surroundings in two-
dimensional polar coordinates, relative to its measurement origin. Its measurement ori‐
gin is marked by a circular indentation in the center of the optics cover. If a laser beam
strikes an object, the position of that object is determined in terms of distance and
angle.
With the MRS6000, this is done in 24 layers. Here, 4 scan planes with 6 layers each
are detected one after the other.

The angular resolution is 0.13°. This produces a fine network of measuring points (3D
point cloud) for the scanned working range (120° horizontal, 15° vertical).

Range finding
The device emits beams pulsed by a laser diode. If the laser beam is reflected by an
object, the reflected beam is received by the sensor.
