Abstract
A method for detecting a degree of wetting of a glass pane, in particular a windscreen of a motor vehicle, is provided. A transmitter is arranged on the inside relative to a glass pane and emits electromagnetic waves, which are reflected according to the total reflection principle on the outer, from the transmitter's point of view the opposite surface of the glass pane, and which are received by a receiver arranged on the inside relative to the glass pane. Electromagnetic waves are emitted further from a transmitter. Waves pass through the glass pane and are scattered on particles or droplets in front of the glass pane and are received by a receiver arranged on the inside relative to the glass pane.
