Abstract :
The new technology is offered for measurement of acoustic wave frequency. The method is based on using the Bragg light diffraction on the hypersonic transversal acoustic wave in a gyrotropic crystal. Measurements have been carried out with help of LiNbO3 crystal oriented along the crystallographic axis of the third order at the average frequency 1.0 GHz. The dependence of the diffracted light intensity from the quantity of specific rotation was used for determination of the acoustic wave frequency by the appropriate model equation accurate within 0.1%.
