Imaging of Surface Wave Slowness

Abstract
An experimental method has been devised for imaging the acoustic surface wave slowness (inverse of the phase velocity) in anisotropic solids. This technique utilizes a specially designed broadband, line-focus ultrasonic transducer to sense the leaky surface waves as well as leaky pseudo-surface waves emanating from a solid immersed in water. By rotating such a transducer about its symmetric axis normal to the solid surface, the orientation-dependent time waveforms can be obtained. These waveforms are readily transformed into a surface wave slowness image with a simple algorithm.Citation
