Anordnung zur optischen Abstandsbestimmung einer reflektierenden Oberflaeche

DE 10323336 B UPAB: 20041027 NOVELTY - Arrangement for optical distance determination of a reflecting surface (4) on to which light from a first optical fiber is directed with reflected light routed through the same optical fiber or a second fiber to a stationary detector. The incident and reflected light passes through a collimating optical element (2) and at least two focussing optical elements (3'). The focussing elements are arranged at predefined distances to each other and have their optical axes parallel to the collimator axis. USE - Optical arrangement for determining the distance to a reflecting surface. ADVANTAGE - The distance to a reflecting surface can be determined with higher sensitivity.
