Abstract
(EN)
In some embodiments, an apparatus and a system, as well as methods, may operate to include acquiring eddy current data from at least two concentric pipes. Further activity may include determining spatial frequency content of the eddy current data, and determining locations of defects in each of the pipes based on the spatial frequency content. Additional methods, apparatus, and systems are disclosed.
