Imperium is developing two alternate configurations of its Acoustocam portable ultrasound imaging camera under the DOD’s SBIR Program to meet NAVAIR’s requirements for quickly and easily inspecting composite structures for non-visible damage. A through-transmission ultrasonic camera system will detect skin-to-core disbonds in thin honeycomb structures such as helicopter rotor blades. A simpler, pulse-echo version of the Acoustocam will detect defects such as delaminations, disbonds, and corrosion in composite laminate and metallic sheet- or plate-like structures when only one side of the structure is visible. The Acoustocam has advantages over pulse-echo or through-transmission beyond its speed and simplicity of use: digital imaging technology allows the user to archive all data recorded and use image processing methods to enhance defect detectability. Archived images can be compared to track damage progression. Future upgrades will add encoders to provide location data that can be used to “stitch” the individual frames together to create seamless images of larger structures and wireless data transfer to remote viewing locations.

Industrial aluminum slabs are typically produced by blending small amounts of copper or manganese in a reservoir of molten aluminum that is rapidly cooled, a process known as direct-chill casting. Variations in the way these elements solidify can yield uneven results that weaken the final product.
