LRF 7047- Integrator Manual
Mirror-like objects
The accuracy and range performance on mirror-like objects such as water, glass surfaces or reflective
traffic signs can cause incorrect measurements or no measurement results at all.
NOTICE
Avoid mirror-like surfaces and aim at a target next to it. It can cause incorrect measurements.
Kinetic tremor
If the host system with an integrated LRF module is firmly installed or mounted (e.g. on a Tripod), longer
distances can be measured more easily. If the LRF module is shaking during a measurement, it can lead
to wrong or no measurement results. This is due to the fact that only a few pulses hit the target during the
measurement. The example below shows a laser beam with 0.5 mrad divergence on targets in 2 km
distance. The range measurement on the large NATO target is still OK, but on the man size target it is
lost.
 Firmly mounted modules allow a longer range, e.g. on tripod.
