Filed: 1997-05-20
Abstract: A compact rain sensor for mounting on the inner surface of a windshield includes collimator lenses and a detachable prismatic coupler to facilitate the mounting of emitters and detectors on a circuit board which is positioned parallel to the inner surface of the windshield. A thin optical coupler is adhesively secured to the windshield. A sensor housing is detachably secured about the outer edges of the coupler. Within the sensor housing, surface-mounted infrared emitters and detectors, as well as signal processing circuitry, are all mounted on a single printed circuit board secured in the housing. When the sensor housing is mounted on the coupler, the printed circuit board is parallel to the inner surface of the windshield and in close proximity thereto. In operation, a light beam from the emitter enters the windshield at a forty-five degree angle and is reflected back from the outer surface of the windshield to the detector, which generates a control signal based on the amount of light reflected from the outer surface. Moisture on the outer surface of the windshield reduces the amount of light reflected to the detector. Surface mounted emitters and detectors, which are very cost and space efficient, are mounted on the circuit board with an initial optical axis perpendicular to the circuit board. In order to achieve the desired forty-five degree angle of entry into the windshield, the light beam emitted from the emitter is reflected, refracted, and collimated prior to entry into the windshield by collimator lenses mounted on the circuit board and by prismatic regions formed in the coupler.
