Usage of lens shield

KDP3 has provided 2 lens shields for masking the undesired detection area.
Each lens shield has 2 layers, each layer includes 6 small pieces of shield and
each small piece of shield can cover 30o detection area.
For example, to install the detector at the height of 2.5m, the detection range
can reach up to 2m diameter if the complete lens shields have been used,
and up to 6m diameter if only the A layer of lens shield has been used
(See FIG.22).
The whole lens shield is used.
