A velocity calibrator based on a laser driven Michelson interferometer was designed for a73Ge Mössbauer spectrometer in the range of 100 to 500 μm/sec. The conventional method of counting the interference fringes cannot be used in this case because the displacement only spans about 3 to 15 μm and only a few fringes can be observed during one velocity sweep. The velocity calibration obtained this way was compared with the calibration obtained from57Fe measurement, and excellent agreement was found between the two methods.
