    摘要： A method for inspecting a part is provided. The method includes applying a number of multifrequency excitation signals to a probe to generate a number of multifrequency response signals for the part being inspected. The method further includes performing a multifrequency phase analysis on the multifrequency response signals to inspect a subsurface of the part. An inspection system is provided and includes an eddy current (EC) probe configured to induce eddy currents in a part. The system further includes an eddy current instrument coupled to the EC probe and configured to apply multifrequency excitation signals to the EC probe to generate multifrequency response signals. The system further includes a processor configured to analyze the multifrequency response signals from the EC instrument by performing a multifrequency phase analysis, to inspect a subsurface of the part.

    摘要： A method of assembling an eddy current probe for use in nondestructive testing of a sample is described. The method includes positioning at least one substantially planar spiral drive coil within the eddy current probe, such that the drive coil is at least one of adjacent to and at least partially within a flexible material. The method further includes coupling at least one unpackaged solid-state magnetic field sensor to the at least one drive coil.

    摘要： A non-planar part has a non-planar surface such as an edge, and may contain an anomaly such as a crack. The non-planar part is inspected using an eddy current technique. The method includes providing the non-planar part having the non-planar surface thereon, driving an eddy current probe at two or more frequencies, measuring an eddy current response signal of the non-planar part at each frequency, and performing a multifrequency phase analysis on the eddy current response signals.
