Electromagnetic Imaging Methods for Nondestructive Evaluation Applications

Electromagnetic nondestructive tests are important and widely used within the field of nondestructive evaluation (NDE). The recent advances in sensing technology, hardware and software development dedicated to imaging and image processing, and material sciences have greatly expanded the application fields, sophisticated the systems design and made the potential of electromagnetic NDE imaging se...

ELECTROMAGNETIC NONDESTRUCTIVE EVALUATION: PRESENT AND FUTURE Keynote lecture

1. Introduction Eddy current examination has its origin with Michael Faraday's discovery of electromagnetic induction in 1831. Faraday was a chemist in England during early 1800's and is credited with the discovery of electromagnetic induction, electromagnetic rotations as the magneto-optical effect, diamagnetism and other phenomena [1]. Faraday discovered that when a magnetic field passes thro...

Shearography and Applications in Nondestructive Evaluation

This article reviews shearography and its applications in nondestructive testing. Shearography is a laser-based technique for full-field and non-contacting measurement of surface deformation (displacement or strains). Despite being a relative young technique, it has already received considerable industrial acceptance, in particular, for nondestructive testing. One major difference of shearograp...

Electromagnetic Thermography Nondestructive Evaluation: Physics-based Modeling and Pattern Mining

Electromagnetic mechanism of Joule heating and thermal conduction on conductive material characterization broadens their scope for implementation in real thermography based Nondestructive testing and evaluation (NDT&E) systems by imparting sensitivity, conformability and allowing fast and imaging detection, which is necessary for efficiency. The issue of automatic material evaluation has not be...
