SYSTEM AND METHODS FOR INSPECTING INTERNAL CRACKS |
摘要 |
A method for inspecting an internal cavity in a part is provided. The method includes inserting a probe into the internal cavity. The method also includes controlling movement of the probe using a defined scan path to scan the probe over a region of interest in the internal cavity. The method also includes applying multiple multifrequency excitation signals to the probe to generate a number of multifrequency response signals. The multifrequency excitation signals are applied at multiple positions within the internal cavity. The method further includes performing a multifrequency phase analysis on the multifrequency response signals to inspect the internal cavity.
