The invention relates to a device for detecting rain on a pane (2). The device comprises a camera (1), a lighting source (3) for emitting light (h, o, p) and a diffusion element (6). The light (h, o, p) emitted by the lighting source (3) emerges as a light sheet(s) from the diffusion element (6). The camera (1), the lighting source (3) and the diffusion element (6) are designed and arranged in such a way that the camera (1) can detect a signal from the light (h, o, p) or an imaging (i1, i2) of the light sheet(s) which is emitted by the lighting source (3), impinges through the diffusion element (6) on the pane (2) and is reflected by the pane. In particular, in this case, the signal detected by the camera (1) or the light sheet(s) (i1, i2) correlate(s) with light from the lighting source (3) which is reflected or scattered at the inner face (2.1) or outer face (2.2) of the pane and/or at a raindrop.
