Opto-electronic sensor with evaluator electronics especially for vehicle windscreens has radiation conductor copying test light emerging from transmitters through test surface to at least two receivers

摘要

The sensor device has a radiation conductor which copies the test light emerging from at least two transmitters (5) through a test surface (2) formed on the conductor to at least two receivers (6). The transmitters and receivers are arranged in one plane, preferably integrated in the conductor . A measuring signal is produced. The radiation conductor has an inner focal plane in which the transmitters and receivers are arranged in pairs axially symmetrical and the optically active faces are arranged so that the test light from one of the transmitters is copied through focussing on the axial of symmetric on the opposite receiver.
