Analysis and Procession of Sensitivity Distribution of Electronic Capacitance Tomography

Yan Jie,Guo Hongxing,Wang Yanping (College of Electronic Information,Wuhan University,Wuhan 430072) Chang Hongsen,Bao Zongti (Dept.of Physics,South China Normal University,Guangzhou 510631)  
This paper investigates the sensitivity distribution of two phase flow electrical capacitance tomography,and points out that the cause of low image reconstruction fidelity at the pipe center is that the former algorithm uses the same weighting factor in different flow type.It presents a new iterative algorithm using different weighting factor in different flow type.According to the result of computer simulation,this improved algorithm is able to greatly increase the imaging fidelity of any flow phase concentration.It's proved to be better than before.
