Non-destructive techniques are used widely in the metal industry in order to control the
quality of materials. Eddy current testing is one of the most extensively used non-destructive …

Pulsed eddy current (PEC) non-destructive testing and evaluation (NDT&E) has been
around for some time and it is still attracting extensive attention from researchers around the …

There is currently a requirement in many industries to inspect carbon fiber reinforced plastic
(CFRP) components, such as those used in aircraft and for wind turbine blades to identify …

High-speed inspection of inner diameter (ID) and outer diameter (OD) surface defects on
thick-wall steel pipes is an important aspect to advance the pipeline inline inspection (ILI) in …

Hidden defect characterisation in some complex structures is difficult. Pulsed Eddy Current
(PEC) imaging based on rectangular excitation coil is investigated in this paper and hidden …

Deep defect detection for ferromagnetic materials is a challenging task for Eddy Current
testing (ECT) due to the skin effect of the low penetration depth. Pulsed Eddy Current testing …

Eddy current testing can be used to interrogate steels but it is hampered by the lift-off
distance of the sensor. Previously, the lift-off point of intersection (LOI) feature has been …

Lift-offs of the sensor could significantly affect the measurement signal and reconstruction of
material properties when using the electromagnetic (inductive) eddy current (EC) sensor …

Defect detection in ferromagnetic substrates is often hampered by nonmagnetic coating
thickness variation when using conventional eddy current testing technique. The lift-off …

Previously, various techniques have been proposed for reducing the lift-off effect on the
thickness measurement of the nonmagnetic films, including the peak-frequency feature and …
