A FAST PHASEMETER FOR INTERFEROMETRIC APPLICATIONS WITH AN ACCURACY IN THE PICOMETER REGIME

Paul Köchert, Jens Flügge, Christoph Weichert, Rainer Köning, Eberhard Manske
  • Abstract:
    The lock-in principle is a preferred method to determine the phase difference between elec trical signals of heterodyne interferometer. A phase meter based on this method was devel oped at PTB allowing to detect fractions of an optical fringe in the range of a few picometers, which is verified by experimental results.
