Abstract
The invention relates to a light barrier system, comprising at least two reflection light barrier devices, each of which is configured to emit a light beam and to detect a reflected light beam, wherein the light barrier system comprises a reflection body, which is configured to reflect back light beams emitted from at least two different directions in parallel, which are spaced apart at an angle of at least 20°, wherein the at least two reflective light barrier devices are arranged in such a way that they emit light beams from different directions onto the same reflection body in order to monitor at least two spatially different areas. In a further aspect, the invention relates to the use of a reflection body.
