Reports on Progress in Physics, 1992 Acoustic microscopy enables one to image the interaction of acoustic waves with the elastic properties of a specimen with microscopic resolution. A lens with good focusing properties on the axis can be used for both transmitting and receiving the signal, and an image is formed by scanning the lens mechanically over the specimen.

Analysis of Using Acoustic Microscopy to Evaluate Defects in Spot Welding Joints
Archives of Metallurgy and Materials, 2016 The article presents the possibilities of using acoustic microscopy to evaluate defects in resistance spot welding joints. For this purpose, the welded joints were made from two grades of aluminium plates EN AW5754 H24 and EN AW6005 T606, which were then
