摘要： In an optical position-measuring device for recording the relative position of a scanning unit and a measuring standard, the scanning unit includes a light source, first annular scanning graduation, reflector element, beamsplitter element, and detection unit. A beam emitted by the light source impinges on the measuring graduation and is split into at least two partial beams of rays. The partial beams propagate toward the scanning unit, impinge the first scanning graduation on the reflector element, are reflected through the first scanning graduation toward the measuring graduation, impinge the measuring graduation, propagate toward the scanning unit and undergo superposition, and are deflected by the beamsplitter element toward the detection unit. There, a plurality of positionally dependent, phase-shifted scanning signals can be recorded. The first scanning graduation focuses the partial beams from the measuring graduation at the reflector element, thereby recollimating the partial beams to be reflected toward the measuring graduation.

摘要： An interferometer includes a light source and a beam splitter, via which the beam of rays emitted by the light source is split into a measurement beam and a reference beam. The measurement beam propagates in a measuring arm extending in a first direction between the beam splitter and a measuring reflector. The measuring reflector brings about an offset perpendicular to the direction of incidence between the measurement beam falling on it and the measurement beam reflected back by it. In a reference arm extending in a second direction, the reference beam propagates between the beam splitter and a reference reflector. In addition, the interferometer has a detector system, to which the superposed and recombined measurement beam and reference beam are able to be supplied, and via which a distance-dependent interference signal with respect to the position of the measuring reflector is able to be generated. The measuring reflector in each case includes at least one transmission grating as well as a reflector element.

摘要： An optical distance-measuring device includes a light source, and an interferometer unit having a measuring retroreflector, stationary reference retroreflector, beam-splitter element, beam-recombiner unit, and detection unit. The beam of rays emitted by the light source swivels about the center of the reference retroreflector. The beam of rays arriving from the light source splits via the beam-splitter element into a measuring beam and reference beam. The measuring beam propagates in the direction of the measuring retroreflector, and the reference beam propagates collinearly with the measuring beam in the direction of the reference retroreflector. The measuring beam is reflected back by the measuring retroreflector and the reference beam is reflected back by the reference retroreflector in the direction of the beam-recombiner unit, the measuring beam traveling symmetrically relative to the reference retroreflector prior to and after reflection at the measuring retroreflector.
