Three- dimensional industrial process tomography using electrical and electromagnetic tomography: recent developments

Electrical and Electromagnetic imaging are widely used in many application areas. Most works are done in 2D imaging mode. Recently, volumetric (3D) imaging of passive electromagnetic properties using low frequency electrical and electromagnetic imaging is being developed. This paper presents the latest results of 3D electrical and electromagnetic tomography imaging. The results of experimental data will be presented based on most commonly used finite element modelling of the forward model and the standard Tikhonov regularized inverse solution. Challenges and opportunities will be discussed in presentation.
