Classification: G09B

Abstract:
A method for injecting virtual flaw signals into a nondestructive test system, comprising the steps for:moving a test probe over a test piece by an inspector; providing an excitation signal from the nondestructive test system to the test probe and a virtual flaw injection circuit; determining virtual flaw parameter signals from test probe position signals and a stored virtual flaw map for the test piece; sending the virtual flaw parameter signals and an output signal from the test probe to the virtual flaw injection circuit; processing the excitation signal and the test probe output signal using the virtual flaw parameter signals for generating a virtual flaw response signal by the virtual flaw injection circuit; transmitting the virtual flaw response signal to a test probe input of the nondestructive test system; and displaying actual and virtual flaws to the inspector from the nondestructive test system.
