Figure 10
– Distance to reflecting surfaces
It is thus important to respect a minimum distance between the AOPD and reflecting surfaces. The minimum distance,
D
sr
, depends on the:

operating distance between active and passive units,

effective aperture angle (EAA) of the AOPD):
For a Type 4 AOPD, EAA
MAX
= 5° (
α = ± 2.5°).
The diagram below shows the minimum distance to the reflecting surface (D
sr
), based on the operating distance for a
Type 4 AOPD:
