Instead of the surface of the mirror, it is possible that the object on which the deflected laser
beam is incident may be detected.
Fig. 9:
Object smaller than diameter of the laser beam
Objects that are smaller than the diameter of the laser beam cannot reflect all the energy
of the laser light (
). The energy in the portion of the laser light that is not
reflected is lost. This means that the scanning range is less than would be possible
theoretically based on the surface of the object.
3.5.1
Scanning range of the LMS
The scanning range of the LMS is dependent on the remission of the objects to be detected.
The better a surface reflects the incident radiation, the greater the scanning range of the
LMS. The diagrams in
indicate the relationship between remission and detectability.
Fig. 10:
Scanning range of the LMS as a function of the target remission
Up to a distance of 10 m (32.81 ft) the LMS can detect objects from 3% remission. At a
distance of 65 m (213.25 ft) objects are only detected if they have a remission > 100%.
