Non-destructive Evaluation of components is a need throughout much of the manufacturing industry that involves high value parts. The aircraft companies are a prime example of this need. The fleet of commercial and military aircraft that is in use worldwide today is aging and consequently it has become critical to develop an economical real time inspection of aircraft components such as wing structures, engine mounts, turbine blades, and various other critical components in modern day aircraft. The materials used in aircraft structures vary substantially today, indeed it is commonplace to see exotic composite materials as well as the more conventional materials such as aluminum and titanium.
