Ground detection
Ground detection recognizes objects lying on the road, as well as steps or depressions.
The sensitivity of the filter can be adjusted to different road surfaces, from smooth/
level (
-
) to rough/uneven (
+
).
It should be noted that the ground detection functionality is only available on the first or
last echo and at distances of a maximum of 30 m. If the condition of the surface is
defined as rough/uneven, flat objects lying on the ground may not be classified as
objects.

Multi-layer technology
The multi-layer technology of the device allows compensation of the pitch angle through
24 layers at different vertical angles, when attached to a vehicle for example. In this
way, the device detects the object reliably, for example even when the vehicle acceler‐
ates or brakes.
3.5.9
Scan data output
The device has 4 polygon mirrors that each detect one plane. 6 layers are detected per
plane.
The data is output for each scan. Every 100 ms, the data is output with 24 telegrams in
each case (1 telegram per layer). The duration of data output for all data of a scan
depends on the connection speed. At highest transmission speed (1 GBit Ethernet), the
output duration is approx. 8 ms.
Marks for scan (scan counter), plane (time stamp) and layer (layer angle) are included
in the data telegram for data assignment.
