    摘要: A method for inspecting a component having a surface profile that includes a local minima and a local maxima. The method includes generating a raw image of a component under test utilizing an eddy current inspection system, decomposing the raw image into a plurality of images wherein each image includes a different frequency component, and reconstructing at least one final image of the component that includes frequency components that are relevant to an eddy current flaw signal.

    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.
