Abstract
Acoustic microscopy have increasingly become of use for visualization of microstructure and for characterization of acoustic properties of materials1,2). Since scanning acoustic microscope (SAM) was first introduced by Lemons and Quate3), almost all SAM images and V(z) curves have been obtained by using Quate type transducers. This transducer comprises a planar transducer deposited or bonded on the rear surface of a sapphire buffer rod whose front surface is shaped into a concave sphere (acoustic lens) to transmit a focusing acoustic beam in coupling liquid, e.g., water.
