Diagram of
shows the minimum distance from the reflecting surface (Dsr), based on the
operating distance:
Fig 14 - Minimum distance from reflective surface
The formula to get Dsr is the following:
For ESPE Type 2:
Dsr (m) = 0.6 for operating distance < 3 m
Dsr (m) = operating distance (m) x tg 2a for operating distance >= 3 m
