Principle of operation
3.5.1
Measurement principle
The device is an opto-electronic LiDAR sensor that scans the outline of its surround‐
ings with the help of laser beams without making contact. The device measures its
surroundings in two-dimensional polar coordinates, relative to its measurement origin.
This 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 MRS1000, this is carried out in 4 spread-out scan planes (layers 1 to 4).

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.
The distance to the object is calculated on the basis of the time that the pulsed light
beam requires to be reflected and received by the sensor.

The device uses SICK’s own HDDM+ (High Definition Distance Measurement plus)
technology. With this measurement process, a measured value is formed statistical
evaluation of multiple single pulses. The multi-pulse feature of HDDM+ evaluates up
to 165,000 echoes per second with every scan. Every single HDDM+ measured value
output therefore provides even more information because it is not just composed of
