Abstract

The use of reflection acoustic microscopy with spherical lens for quantitative nondestructive evaluation has been studied in the past both from the experimental and theoretical point of view. The basic results have shown that the output of the microscope’s transducer is sensitive to the near-surface material’s elastic properties. Based on this, a variety of applications of the acoustic microscope to material science study have been developed [1]. Measurements of surface wave velocity and elastic constants in solids [2,3,4], detection and characterization of discontinuities of the elastic constants in solids due to cracks, interfaces, etc. [5], and measurements of dispersion relation for leaky Rayleigh wave in simple and layered systems [4,6] are a few examples of problems which can be investigated by means of the acoustic microscope.
