Abstract

A novel method of fully noncontact excitation and registration of surface acoustic waves (SAW) in constructional materials has been suggested and theoretically substantiated. It is based upon laser-induced excitation of SAW pulse and registration of thermal response that accompanies dilatation in the acoustic wave. The method is especially convenient for the samples under elevated temperatures.
