Position-measuring system, having scanning units multiplexed to light sources and detectors, for optically scanning a measuring standard and method for operating such a position-measuring system

摘要

A position-measuring system includes a plurality of scanning units for the optical scanning of at least one measuring standard, the scanning units being coupled optically to a plurality of light sources and a plurality of detectors. Disposed between the scanning units and the detectors are a plurality of demultiplexers, via which in each case at least two scanning units are coupled to one detector.
