Abstract

The paper presents theoretical and experimental investigations of the structure of the spatial distributions of strain amplitudes for an oscillating surface using an optical interferometer. A conventional Michelson interferometer and an interferometer containing an acousto-optic cell have been studied. It has been shown that the maximum possible sensitivity of the device is 0.001 Å, with the minimum strain amplitude reaching 0.001 Å. Practical advantages of the interferometer with an acousto-optical cell have been realized.
