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 visible light pulse and
receiving the reflected pulse from the object is measured in the device. Due to the
constancy of the speed of light, this time is a distance measurement.
In comparison with other distance measurement processes, time-of-flight mea-
surement 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.
In the integrated measurement data evaluation, the measurements are compared
with up to four configured monitoring fields. The results can be logically linked in
two levels and read out at up to four outputs. Up to four inputs can be integrated
into the logical linking of the monitoring fields. The laser scanner has four I/Q con-
nections so that an appropriate combination of inputs and outputs is possible.
