2.2.2. Minimum distance from reflecting surfaces

Reflecting surfaces placed near the light beams of the AREAscan

device (over, under or laterally) may cause passive reflections; these

reflections could compromise the recognition of an object inside the

controlled area (see Fig.1).

Fig. 1

However, if the receiver detects a secondary beam (reflected by the

side-reflecting surface) the object cannot be detected, even if the main

beam is interrupted by the entering object.
