2-D Laser Scanner
Product Description
4.2
Functional Principle
The laser scanner works according to the principle of Pulse Ranging Technology
(PRT). As part of this principle, the time between sending a light pulse and
receiving the reflected pulse from an object is measured in the device. Due to the
constancy of the speed of light, this time is a measurement of distance.
In comparison with other distance measurement processes, runtime
measurement is affected very little by any disturbances in the measuring
environment. As a result, this measurement process can be used with a high level
of accuracy even under tough everyday industrial conditions. The light source and
light receiver are located in the rotating sensor head.

Indicators and Controls
Note!
Influence of ambient conditions
The speed of light depends on the air temperature and barometric pressure.
The influence of the air temperature amounts to 1 ppm/K.
The influence of the barometric pressure amounts to -0.3 ppm/hPa.
These faults must be taken into consideration by the user in the case of longer
distances.
In the operating range (-10
°
C ... +50
°
C) this fault amounts to 0.6 mm at a
distance of 10 m.
No.
