Abstract: The common working procedure of Electrical Impedance Tomography (EIT) needs to take a reference measurement when the phantom is full of homogenous continuous phase. However, in industrial operations, sometimes it is impracticable for practical process to have a homogenous continuous phase in the phantom for the purpose of taking a new reference for EIT. In order to overcome the difficulties raised by the traditional EIT in industrial applications, the frequency-difference EIT (fdEIT) adopted in medical applications could be an alternative solution for this problem. In this study, the characteristics difference of multiple materials at two different frequencies is used to reconstruct the tomographic image. A Laplacian of Gaussian (LoG) operator is introduced to the inverse problem to improve the image quality. A method of selecting two optimal frequencies is discussed as well. The performance of our system is verified on the simulations and on the experimental rig.
