Abstract
Automated, rapid, non-destructive inspection of large scale composite structures is an ongoing challenge for just about every NDI technology currently deployed in the aerospace, power generation, wind energy, and automotive industries. Both hardware and software limitations have dictated the level of inspection throughput, accuracy and reliability. In Phase I, TWI developed and demonstrated feasibility of a novel technique to thermographically inspect large composite areas at a large standoff without expected trade-off in performance. Using a sophisticated signal processing scheme and projected, modulated optical excitation, we demonstrated detection of subsurface features in composite materials at a working distance of 45 feet from the target. The results were comparable to (and in some cases better than) results from commercial flash thermography systems operating at close range. In Phase II, we shall build on the Phase I program and develop a commercially viable solution (prototype) - LASLAT (Large Standoff / Large Area Thermogrpahy) offering flexibility so it can be readily adapted to a broad range of applications requiring rapid large area NDI with a focus on wings of C-130J family of aircraft operated by our military.
