Abstract
Disclosed is a system and method of determining the test surface profile and compensating the gain amplitude when using time reversal focal laws in ultrasound non-destructive testing. Computer simulations are used to compute the diffraction field at time of incidence of the transmitted parallel wave front on the test surface. Knowledge of the surface profile and the diffraction field allows determination of coverage at the test surface and improved accuracy of flaw sizing.
