Abstract

Many materials contain a random microstructure that can have an adverse effect on ultrasonic measurements (reducing signal strength, increasing noise and reducing accuracy) through scattering and aberration of the acoustic field. To account for those adverse effects we have developed a phase screen model alongside the stochastic wave equation. This two fold approach allow us to directly model the field for adaptive correction and to characterise material from the statistical properties of experimental measurements.
