The Pacific Northwest National Laboratory (PNNL) has developed a portable, battery-operated handheld ultrasonic device that provides non-invasive container interrogation and material identification capabilities. The Acoustic Inspection Device (AID) performs an automated analysis of the return echoes to identify the material, and detect contraband in the form of submerged packages and concealed compartments in liquid filled containers and solid-form commodities. This device utilizes a database consisting of material property measurements acquired from an automated ultrasonic fluid characterization system called the Velocity-Attenuation Measurement System (VAMS).
