  • Method and apparatus for eddy current detection of material discontinuities
    Publication number: 20060202689
    Abstract: A method of eddy current testing without the need for lift-off compensation. Signal response features similar to those used in pulsed eddy current techniques are applied to conventional (harmonic) eddy current methods. The described method provides advantages in terms of data storage, since only two response parameters, the amplitude and phase, are sufficient to reconstruct any sinusoidal signal, therefore allowing for scanning of large surfaces.
