Abstract
This thesis project report describes the research done by the author under the supervision of Prof. J. Tapson. The area of research is an investigation of sine-wave drive for a frequency division multiplexing (FDM) electrical impedance tomography (EIT) system. This thesis was commissioned by Prof. J. Tapson, on the 1 st of November 200 1. The goals were as follows: 1. Investigate the research done on this project by previous researchers. 2. Investigate the current applications in which capacitance, resistance and impedance tomography are used in research level and in industry. 3. Design and develop a working 8-electrode impedance tomography system. Also, make provisions for a possible upgrade of the 8-electrode system to a 16-electrode (16 capacitance and 16 resistance electrodes) system employing FDM and using sine-wave excitation. 4. VerifY and compare the performance of the 8-electode impedance tomography system to the previous research done by Teague [53], for static configurations of multi-phase air-gravel-seawater mixtures. 5. Evaluate the ability of the system to differentiate between air and gravel mass in static situations. 6. Draw conclusions regarding the performance, effectiveness and limitations of the system. 7. Make recommendations for future project developments. 8. Submit the thesis by the 28th of March 2003.
