Ultrasonic microscope system

Patent ·
OSTI ID:6265375
An ultrasonic transmitter-receiver for radiating a focused ultrasonic beam and a sample are moved relative to each other in the axial direction of the ultrasonic beam. A reflected wave from the sample is received and a curve V(Z) of variations in the level of the reflected wave with respect to the relative movement is obtained. A reference level of interference of a directly reflected wave and a leaky elastic wave is subtracted from V(Z) to perform waveform processing. The waveform processing output is subjected to a waveform analysis, and from the analysis results, the velocity and/or the attenuation of the leaky elastic wave are calculated.
