Zusammenfassung:	PCT No. PCT/DE95/00144 Sec. 371 Date Aug. 15, 1996 Sec. 102(e) Date Aug. 15, 1996 PCT Filed Feb. 3, 1995 PCT Pub. No. WO95/23082 PCT Pub. Date Aug. 31, 1995A rain sensor in which an optical effective radiation (11) is subjected to at least one total reflection in a sheet of glass (16). The effective radiation (11) coupled out of the sheet of glass (16) into a coupling-out part (22) at the end of a measuring segment (24) and possibly present interference radiation (31') impact a separating surface (25) of the coupling out part, at which surface only one of the two radiations (11, 31') is totally reflected. The separating surface (25) permits a separation of the interference radiation (31') from the effective radiation (11) before it impacts a radiation-measuring device (30). The rain sensor of the invention is particularly suited for use in motor vehicles in connection with a windshield-wiping system which is operated automatically as a function of the rain sensor.
