Abstract

Corrosion quantification is an important aspect of aircraft skin NDE. Eddy current and pulsed-eddy current techniques are frequently used to measure corrosion. Corrosion quantification from these NDE measurements is typically an ill-posed inverse problem. A sequential Monte Carlo (SMC) based technique is proposed here to solve this inverse problem by fusing multiple NDE measurement modes. Inversion results are compared with digital x-ray thickness mapping to quantify the efficacy of the proposed technique.
