Transmission detector for a window body, in particular the windshield of a motor vehicle, and a cleaning device for a viewing area of a window body

A transmission detector for a windshield window body, comprising:

• an optical sensor device, including an imaging system having a wide-angle lens, a position-sensitive optical detector and at least one aperture;
• an analyzing system for analyzing image data recorded by the optical detector, wherein sections of a surface of the windshield window body, having an area that approximately covers an entire span of the windshield window body, are projected on the optical detector;
• and
• at least one actuator for controlling the at least one aperture opening.
