A device for detecting rain on a pane includes a camera, a lighting source for emitting light and a diffusion element. The light emitted by the lighting source is diffused through and emerges as a light sheet from the diffusion element. The camera, the lighting source and the diffusion element are configured and arranged so that the camera can detect a signal from an image of the light sheet that is emitted by the lighting source, diffused through the diffusion element, impinges on the pane and is reflected or scattered by the pane and/or a raindrop on the pane. The signal detected by the camera is evaluated to detect whether there is rain on the pane.
