Inversion of Lift-Off Distance and Thickness for Nonmagnetic Metal Using Eddy Current Testing

IEEE Transactions on Instrumentation and Measurement, 2020
For the electromagnetic eddy current testing, various methods have been proposed for reducing the lift-off error on the measurement of samples. In this paper, instead of eliminating the measurement error caused by the lift-off effect, an algorithm has been proposed to directly measure the lift-off distance between the sensor and non-magnetic conductive
