Abstract

An optical method for determination of local velocity of surface acoustic waves according to which surface acoustic wave is excited on the surface of a sample, with directing probing optical beam to the surface, this is directed to photo-receiver after reflection. The optical beam is expanded by means of forming optical system, and with displacement of the photo-receiver in parallel to the direction of propagation of acoustic surface wave a signal is registered in two regions of optical beam, by the value of spatial displacement of the photoreceiver and time shift between the signals velocity is determined.
