The V(z) measuring technique, i.e. the application of the acoustic micro-scope as a measurement tool is presented and explained. In the measurements, the pressure amplitude distribution on the surface of the lens is controlled in a certain range, enabling V(z) curves to be optimized with respect to oscillation amplitudes obtained for the given material.
V(z) curves obtained with this set-up and calculated from them Rayleigh wave velocities are included in the paper. The possibility of using such a set-up in thin film measurements has been pointed out.
