Abstract (en)
[origin: DE19820630A1] The position detection device uses an optical source (1), provided by a stationary light source and a cooperating stationary optical sensor (6), positioned on opposite sides of a rotating object (7), aligned with one another along a beam axis (5). The rotating object has a diametrical bore (9), for passage of the light beam between the source and the detector in a given position of the rotating object.
