Acoustic Mapping for the Detection of Voids Underneath Aluminum Matting

Through this effort, the team of Materials Systems Inc. (MSI) and Sonic Tech, Inc. (STI) will develop a non-destructive evaluation technique for detection of voids and defects underneath Aluminum Matting-2. The MSI scanning concept fully utilizes its expertise in the design and development of piezocomposite transducer arrays, combined with STI's experience in acoustic system development and signal processing, to develop a system to identify, locate and map surface and subsurface defects on Expeditionary Airfields. The system is lightweight and portable, amenable to scanning large areas at high speed, is self-calibrating and adaptable to scanning multitudes of soil conditions without prior characterization.
