Abstract
Deep subsurface high resolution shear wave imaging using a conventional acoustic microscope and lens is presented. The technique is based on mode conversion phenomena which occur when a focused acoustic beam is incident from water at a material surface. A theoretical framework for the interpretation of the experimental results is discussed. Experimental results are presented using a 50 MHz acoustic lens with a 28° aperture and 11.5 mm working distance in water.Keywords
