Abstract (en)

[origin: WO2012092911A1] The invention relates to a device or a method for detecting rain (4), said device or method comprising a camera (1) and a lighting source (3). The camera (1) is disposed behind a pane (2), in particular in the interior of a vehicle behind a windshield, and focused onto a remote region that lies in front of the pane (2). The lighting source (3) for generating at least one light beam (h; n) that is directed at the pane (2) directs the at least one light beam (h; n) towards the pane (2) such that at least one beam (r2; r2') that is reflected from the outer face (2.2) of the pane impinges on the camera (1). The light quantity of the at least one beam (r2; r2') that impinges on the camera (1) can be measured by the camera (1).
