Abstract

See full text

An optical interferometer including an output-beam beam input for coupling-in an output beam, and a beam splitter device for splitting the output beam into at least one first sub-beam and one second sub-beam, the interferometer being embodied as a heterodyne interferometer by virtue of at least one optical frequency shifter being arranged in the beam path of the interferometer and the interferometer including one or more optical waveguide elements, by which optical waveguides are formed, at least between the output-beam beam input, beam splitter device and frequency shifter. The frequency shifter is arranged in the beam path of the first or second sub-beam.
