Key Technologies Analysis of a Handheld Smart Eddy Current Flaw Detector

In order to solve the in-situ eddy current inspection of aircraft maintenance problems, the author developed a handheld smart eddy current flaw detector. In this paper, in depth descriptions were given to the key technologies in the design and development of the flaw detector, including the ergonomic, modular design and anti-jamming design. Present work might have some theoretical and practical reference guide for the work of in-situ eddy current inspection.
