Introduction
Curtain light barrier
The curtain light barrier consists of three simple light bar-
riers.
The camera system will be triggered if only one of them is
interrupted.
The three light barriers could be built-on in different ways:
parallel, fan-shaped or warped. Thus it is possible to scan
a surface area or rooms for example.
With a vertical adjustment in a fixed frame before the
camera an easily inscect trap can be built.
