Abstract (en)
[origin: WO9946612A1] The invention relates to a special light source which produces a horizontal strip of light. Said strip of light is reflected by objects in the vicinity of the sensor system and conducted to a photoelectric converter by a special imaging device. Said imaging device is configured in such a way that objects situated further away are represented as being somewhat further apart so that an ordinary objective with linear resolution can obtain better position resolution of objects situated further away from the sensor system over the entire imaging area. Advantageously, light-emitting diodes are provided on the optical axis of a cylindrical mirror as the light-emitting elements. The electrical signals emitted by the photoelectric converter are evaluated by an evaluation unit in relation to their position. Using triangulation, said evaluation unit then determines how far away the objects which reflected the light are situated.
