Imaging of Acoustic 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 transducer to sense the leaky surface waves as well as leaky pseudosurface 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 wave forms are readily transformed into a surface wave slowness image with a simple algorithm.Citation
