In this article the eddy current method is used to characterize defects in conductive non-ferromagnetic plates. A special attention is paid to the presentation of results in the form of images. An inverse problem with Tikhonov regularization is solved to obtain the two-dimensional distribution of currents inside the material under test. With this purpose a uniform field probe is used to guarantee...
In this paper, a mobile probe for eddy current testing using inductive sensors and two optical computer mice for position determination is presented. It is a first step in developing an autonomous system that is able to detect flaws in the metallic structure of an aircraft. We present the system implemented and show results of its use to detect a rectangular flaw in a flat aluminum plate.
