| Zusammenfassung | The paper presents an interferometric method of measurement which has been developed to accuratly measure translational and rotational motion quantities at various time dependences over wide ranges of intensity. Modified Michelson interferometers and novel diffraction grating interferometers are applied to transform the displacement and rotation angle into proportional phase shifts of the interferometers' output signals. Interferometer signal processing is based on the pulse counting technique including time interval measurement. A description of the method is given under the aspect of design, modes of operation, system-theoretical behaviour, experimental results and uncertainty. A total measurement uncertainty of 0,1% has been achieved for sinusoidal motion quantities and 0,5% for shock-shaped rectilinear or angular accelerations. Displacement amplitudes from 5 nm to 0,5 m and rotation angle amplitudes from 10-7 rad to more than 10 rad are measured. |
