ABSTRACT:
An arrangement for determining the position, especially the angular position, of a movable body comprises a plurality of tracks which are movable with the body past individual detecting locations for the respective tracks. Each of the tracks includes markings which are distributed along and among the tracks in accordance with a predetermined code. The presence of the markings at the detecting locations is detected by optical detecting signals which are transmitted to a common signal receiver via individual channels associated with the respective detecting locations. The detecting signals are transmitted through the channels chronologically and thereafter assigned to respective time or space slots of a binary coded, position-indicating output signal by means of a control signal generated at a predetermined instant relative to the sequence of detecting signals.
