Measurement of surface displacements resulting from acoustic wave propagation in solids has been used extensively in determining elastic properties of materials [1],[2]. Additionally, examination of acoustic wave propagation in materials has been used as a nondestructive tool in testing the integrity of structures, evaluating the size and position of bulk material defects, determining material dimensions, and in general, characterizing a number of material or structural parameters [3].
