Abstract :
Electrical capacitance tomography (ECT) is a fast imaging technique that visualizes cross-sectional permittivity distribution and may be applied for dynamic process visualization. The design of fast single channel electrical capacitance tomograph is presented in the paper. The elaborated “single-shot” circuit enables higher speed of data acquisition then classical “charge-discharge” and provides similar quality of signal. The setup for 16 electrodes sensor was made. The results of measurements and image reconstruction for simple permittivity distributions are presented.
