In the context of structural health monitoring (SHM), eddy-current testing (ET) is one of several techniques that the maintainers of high-value assets can select as part of an asset life management program. In this article, conventional ET and advanced ET methods are described. The focus is on scanning and point-by-point ET using handheld or automated systems. This article also describes an advanced ET method called the MWM-Array in detail and associated multivariate inverse methods called grid methods. In a companion article on eddy-current in situ sensors, the focus is on surface-mounted and embedded sensors for SHM, using onboard instrumentation or portable data-acquisition units.
