Abstract :
A model-based algorithm is developed for inverting eddy-current data and reconstructing flaws in advanced composite materials. The model incorporates an integral solution that is built around the Green´s function computed in a companion paper. The application of certain least-squares algorithms and a numerical method of analytical continuation are described. Numerical experiments are carried out for a simulated flaw in graphite-epoxy
