Abstract

The method of measurement of space distribution of the surface acoustic wave velocity in nonhomogeneous medium is considered. It is shown that the spatial resolution and error of measurement of the surface acoustic wave velocity are dependent on the magnitudes and its ratio dependents on the step of measurement. The optimization method of the spatial resolution and precision measurement of the surface acoustic wave velocity is proposed. The method is based on the measurement by minimum step size and next processing of the experiment data.
