Paper Abstract

This paper describes a new method of the optimal design of electrical capacitance sensor, which is based on genetic algorithm, and a modified BP algorithm of image reconstruction for electrical capacitance tomography system. In the optimal design of sensor, the evenness of sensitivity distribution, the ratio of maximum capacitance to minimum capacitance and the ratio of full-pipe capacitance to empty-pipe capacitance are considered. In image reconstruction we use the curve of components ratio and threshold valve of pixel gray to improve the performance of BP algorithm. Better quality and accuracy is obtained in experiment.
