Abstract : Techniques for exciting ultrasonic surface waves and their advantages are described. Preferred methods for particular applications are given. Experimental correlation is made to theory for light scattering from surfaces excited with Rayleigh waves. Data are given for velocity and wave amplitude measurements obtained by light scattering. Use of light scattering is considered for investigating surface states, Rayleigh wave dispersion and absorption. (Author)
