Abstract
In an eddy current testing probe, efficiency is improved by multiplexing, at the probe head, signals to and from a large number of coils on the probe head onto a reduced number of signal conductors, and by reusing coils in different measurement configurations in order to provide a higher density of inspection coverage.
