Abstract

A new design of the acoustic microscopy experimental setup is proposed and analyzed in this paper. The proposed microscope can operate at low frequency (0.1 to 3 MHz) and can be efficiently used in fracture mechanics, structural, and geomechanics applications. In the new design there is no buffer rod and the transducer is proposed to have a shape of a cylindrical shell to produce a line focus beam which is necessary to measure material anisotropy. A line receiver is introduced instead of standard transducer-cum-receiver arrangements. A line receiver can receive only one specularly reflected ray and a few critical reflected rays and thus produces less complicated interference pattern or acoustic material signature (AMS) which is easier to analyze.
