SENSOR DEVICE FOR DETECTING MOISTURE ON A WINDOW

摘要

The invention relates to a sensor device for detecting moisture on a window (14). A single emitter (6) generates two measured sections of the sensor on the exterior side of the window (32) which can be exposed to moisture. A fiber optical light guide body (10) which injects the emission radiation (30) into the window (14) comprises structures (22) with which the emission radiation (30) radiated by the emitter (6) is collected or is divided into parallel rays in two different directions.
