DEVICE FOR DETECTING PARTICLES ON A WINDSHIELD
The invention relates to a device (1) for detecting particles (2) on a windshield (3) of an automobile (10) comprising a radiation source (4) emitting optical beams (5) onto the windshield (3), a beam receiver (6) receiving part of the beams (5) sent to the windshield (3) and a control unit (8) controlling the radiation source (4) and evaluating the beams (7) received by said beam receiver (6). According to the invention, in order to reliably detect particles in the field of view of a driver of the automobile (10) in such a device (1) without arranging said device (1) in the field of view of the driver, the radiation source (4) is directed in such a manner that the optical beams (5) of the radiation source (4) hit the windshield (3) in the area of the field of view of the driver of the automobile (10) and the beam receiver (6) is directed to the area of the windshield (3) that is hit by the beams (5) of the radiation source (4).
