Abstract
A simple yet novel method has been developed which is useful for visualizing pressure distributions in acoustic wave fields. The method utilizes the power of contemporary computers to store entire waveforms from the numerous points interrogated in a planar scan. The most useful type of planar scan for the concept is made in the xz plane. The z- axis typically corresponds to the beam axis of a transducer, and the x-axis is an arbitrary axis normal to it. The technique to be discussed will yield moving images of instantaneous acoustic pressure in the xz plane. The concept of looking down at the surface of a body of water, with ripples moving away from a wave generator, is a good analogy.
