A Lamb wave lens for acoustic microscopy [PDF]
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1992 In a conventional scanning acoustic microscope the excited leaky modes contribute significantly to the high contrast obtained in the images. However, all such modes exist simultaneously, and the interpretation of the images is not straightforward, especially in layered media.

Acoustic microscopy of surface cracks
Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1986 Abstract The uniqueness of the acoustic microscope lies in its ability to image the way in which acoustic waves interact with the elastic properties of a specimen with microscopic resolution. A dominant role in the contrast achieved is played by Rayleigh waves that are excited in the surface of the specimen.
