An optical position measuring arrangement including a source of
illumination that generates one or several bundles of illuminating beams,
a measuring graduation that is illuminated by the source of illumination
so as to generate a periodic fringe pattern of a defined fringe pattern
period and a fiber-optical scanning head, wherein the fiber-optical
scanning head scans the periodic fringe pattern. A scanning plate is
arranged in the fiber-optical scanning head, wherein the scanning plate
is matched to the fringe pattern period and scans the periodic fringe
pattern. Fringe patterns, which are phase-shifted in relation to each
other, are generated within a fringe pattern period in bundles of partial
signal beams in the one or several bundles of illuminating beams via a
wavelength-dependent local separation, and the bundles of partial signal
beams are employed for conversion into position-dependent phase-shifted
scanning signals.
