Some layered structures offer separate reflections from adjacent surfaces. In this way interior imaging of semiconductor devices allows failure analysis before opening up the packaging. This can be considered as a kind of high resolution non‐destructive testing, and may prove to be the widest industrial use of acoustic microscopy. Laminated polymer coatings can be imaged by separating the reflections. Layered structures can also be studied through the effect on V(z) of the layers on waves propagating parallel to the surface, either in a plate mode or perturbing the propagation of Rayleigh waves. Adhesion can be observed only through its effect on elastic properties. Some layers can be studied in section, revealing effects of anisotropy and scattering of Rayleigh waves.
