Time-resolved Line Focus Acoustic Microscopy Using Lamb Waves for Material Characterization of Thin Plates

Abstract

In time-resolved acoustic microscopy the specimen is shifted into the defocussed region of the lens and remains at one single position during the measurement. This technique represents an alternative to the V(z) approach in which a high frequency toneburst is used, and the voltage at the transducer of the lens is measured while the specimen is moved within… (More)
