Abstract: An apparatus, system, program product, and method are disclosed for determining the microstructure and properties of materials using acoustic signal processing. An apparatus includes a one or more sensors for sensing information describing a multiphase material using sound waves. The apparatus includes a processor operably coupled to the one or more sensors and a memory that stores code executable by the processor. The code is executable by the processor to receive sound-wave input from the one or more sensors, perform one or more quantitative analyses on the received sound-wave input in the frequency domain, and determine a microstructure of the multiphase material based on results from the one or more quantitative analyses.

Abstract: An apparatus includes an XY scanning mechanism, a first transducer configured to transmit a sound wave, a second transducer configured to receive the sound wave, and a tray configured to hold a material. The tray is coupled to the XY scanning mechanism and located beneath the first transducer and the second transducer is located on a bottom side of the tray below the material. The tray is moved in an XY pattern along an X axis and a Y axis in response to an XY scanning mechanism controller mechanically moving the XY scanning mechanism while the first transducer is positioned in a stationary location along a vertical axis perpendicular to the tray. The first transducer transmits sound waves into the material and the second transmitter receives the transmitted sound waves at each XY position.

Abstract: An apparatus, system, program product, and method are disclosed for a compact immersion scanning system. An apparatus includes an XY scanning mechanism, a first transducer configured to transmit a sound wave, a second transducer configured to receive the sound wave, and a tray configured to hold a material.
