TL;DR: The design of a detection system for the identification of conductive objects based on their response to EM fields and how to construct a two-dimensional image from the measured signals to be used for image processing purposes are addressed.

TL;DR: This study generates physics-mathematical modeling and mining route in the spatial-, time-, frequency-, and sparse-pattern domains and renders the EMT a promising candidate for the highly efficient and yet flexible NDT&E.

TL;DR: A modified variational mode decomposition (VMD) linked wavelet method for EMAT denoising enables to suppress both high-frequency narrowband noise and normal noise in EMAT signals with a large lift-off detection condition.

TL;DR: A 3D eddy current pulsed thermography system by integration the ECPT system with an RGB-D (3D point cloud with RGB texture information) camera, which provides quantified data, including 3D heat distribution and the 3D spatial relationship between defect position, the excitation coil, and the whole specimen shows its potential of quantitative evaluation of the defect characteristics.

TL;DR: In this paper, a full set of PMFL system based on sensor array is used to detect the standard specimens, in order to eliminate the noise and extract the feature, the detecting signal is analyzed and processed by some pre-treatments.
