The paper deals with a measurement system based on a low-rest eddy current
probe for nondestructive testing (NDT) on conducting materials aimed at rec
onstructing the shape and position of thin cracks. The magnetic probe is ch
aracterized, highlighting good repeatability, linearity, and overall accura
cy. A number of different measurement approaches are investigated, in order
to choose the more appropriate for NDT applications. A numerical method wa
s then illustrated; it proves to be able to reconstruct cracks also startin
g from noisy measurement data.
