Abstract

A Michelson interferometer using a CW laser-light source has been used to measure the amplitude of small-order vibrational displacements. Measurements over the surface of a vibrating plate at points 1/2 mm in diameter are reported. Magnitudes of 0.1-5000 A at frequencies of 100 Hz-20 kHz have been measured with higher and lower limits possible. The advantages of the technique are discussed.
