FIELD: measurement technology.
SUBSTANCE: use: to measure angular velocity. Summary of invention consists in the fact that excitation and reception of volumetric acoustic wave passing through the measured object made of isotropic material, wherein the converters are placed on the measured object and the linearly polarized wave is emitted, and the form of the linearly polarized wave which does not coincide with the emitted wave is received, and the angular rotation speed of the object is determined from the amplitude of the received wave.
EFFECT: easy measurement of angular velocity.
