Description

Acoustic microscopy is a powerful ultrasonic technique for flaw detection and material characterization. The instrument usually consists of a piezoelectric transducer and a spherical focusing lens coupled to a surface with water. Generally, the instrument measures the amplitude of the interference of two acoustic signals, the specular reflection which travels along the lens axis between the transducer and the surface and the induced surface wave. The surface wave is generated when the lens is defocused and acoustic energy strikes at the critical angle. The generated wave travels along the surface and radiates energy into the couplant, some of which is detected by the transducer as shown in Figure 1. The amplitude of the interference of these two signals is then converted to an image [1].
