Measurement of small amplitudes of vibration with a laser vibrometer

A method is examined for measuring amplitudes of vibration based on harmonic analysis of the output signal of a Michelson interferometer, with modulation of the frequency of radiation in the reference arm. The advantages of the method are explained and a specific example of its use is given. Translated from Izmeritel'naya Tekhnika, No. 11, pp. 29–32, November, 1999.
