Position tracking and flaw visualization in conductive materials

Research output: Contribution to journalArticlepeer-review


The Eddy current technique has been successfully used in a variety of non-destructive evaluation applications including detection of cracks, measurements of material thickness, examining metal thinning, measurements of coating thickness, identification of materials, and detection of corrosion. This paper shows how positional and eddy-current data are combined to produce a C-scan of flaws in conductive materials. A system that consists of an eddy current probe, a position tracking mechanism, and basic data visualization capability was built and tested. Test results of the prototype are presented and briefly discussed. Improving the accuracy of the measurements using a three-mouse position sensing device is described.
