large portion of the energy emitted can be received by the laser distance measurement de-
vice. Plastic reflectors ("cats’ eyes”), reflective tape and triple prisms have these properties.
At mirror surfaces the laser beam is almost entirely deflected, see
.
Instead of the surface of the mirror, it is possible that the object on which the deflected laser
beam is incident may be detected.
Objects that are smaller than the diameter of the laser beam cannot reflect all the energy
of the laser light, see
. The energy in the portion of the laser light that is not reflect-
ed is lost. This means that the scanning range is less than would be possible theoretically
based on the surface of the object.
