Abstract
Method and implementing apparatus useful in acquiring data on acoustic features within a sample provides a pulsed acoustic probe and a stage system for effecting relative movement between the sample and the probe. The stage system is commanded such that the probe interrogates a non-rectangularly bounded space on the sample surface or within the volume of the sample. Acoustic energy reflected from or transmitted through the sample is sensed. Amplitude signals are developed from the sensed acoustic energy. Data characterizing the developed amplitude signals are stored for subsequent processing.
