ULTRASOUND MICROSCOPY TECHNIQUES TO DETECT DELAMINATION IN STACKED LAYERS

• Abstract:

  We present the theory and some applications of the synthetic aperture focusing technique applied to single transducer ultrasonic data sets. In this technique a virtual source located at the geometrical focal point of the physical transducer is algorithmically generated and thus allows for tighter focusing over a geometrically larger scan volume. We present results from a structural test phantom (two copper wires) and a delaminated specimen.
