Abstract

Subsurface imaging in a non-contacting surface acoustic wave microscope is demonstrated, using mode conversion from Rayleigh to Lamb modes. The fact that, unlike in a conventional acoustic microscope, the technique does not require fluid couplants allows new contrast mechanisms to be used for the quantification of defects.
