2.2.3. Minimum distance from reflecting surface
Reflecting surfaces placed near the light beams of the
SAFE
asy
TM
device (over, under or laterally) can cause passive
reflections.These reflections can compromise the recognition of
an object inside the controlled area (Fig.7)
Fig. 7
However, if the
RX
receiver detects a secondary beam (reflected
by the side-reflecting surface) the object might not be detected,
even if the object interrupts the main beam.
