Analytical Method of Generating Sensitivity Map for Electrical Capacitance Tomography Sensor with Internal Electrode

Abstract:

Electrical capacitance tomography (ECT) is a developing technique for visualization of the dielectric permittivity distribution inside the pipe. Internal electrode or internal structure is frequently encountered issue. In this paper, an analytical method for the circular ECT sensor with internal electrode is proposed to calculate the potential distributions and generate the sensitivity maps. Simulated capacitance data are used to verify the proposed method. The results show that, by using the new method, it can reconstruct high quality images.
