Simplified Synthetic Electrode Strategy for Electrical Capacitance Volume Tomography

Electrical capacitance volume tomography (ECVT) has been used for imaging of flow media in various industrial applications. An ECVT sensor operates in the Laplacian (quasi-static) regime, which exacerbates the ill-conditioning of the associated inverse problem and the imaging resolution. In this paper, we propose a new strategy to increase image resolution through the use of a higher electrode density sensor, which enables electronic scanning by means of synthetic electrodes. We validate the proposed strategy through various simulations.
