WebTheory of Acoustic Microscopy. Acoustic imaging uses the interactions between high frequency beams of transverse sound waves (1-50 MHz) and the test sample to localize areas of different acoustic impedance. Sound waves are reflected at interfaces of different acoustic impedance and attenuated as they travel through the sample material.
