A novel NDE system with an ultrasound sensitive multi-element array has been demonstrated and is currently in product development. The tool is capable of imaging internal defects (e.g. voids, delamination, corrosion) and provide real-time, depth sensitive C-scan information. The system uses a patented sensor array of ultrasound sensitive elements (128 x 128) that generates images in real time. This low cost, portable tool requires no mechanical scanning to acquire C-scan images and can be used for inspection of subsurface corrosion and other flaws. Since the system requires no mechanical scanning, it is be implemented as a handheld probe, not requiring targets to be submerged in a fluid at all. The probe can be used for spot inspection by an operator, or integrated into manufacturing processes for immediate production control over large areas. The application of the system for composites will enable characterization both while they are forming, as well as for field testing of in-service materials. The system operates at thirty frames a second allowing rapid movement over larger areas. This work is supported in part by the Navy SBIR program.
