| Abstract: | Two key technolagy which are capacitance/voltage converting circuit and image reconstruction algorithm of electrical capacitance tomography are introduced in the paper, Capacitance/votage circuit of controllable exciting signal amplitude and two working modes in designed, the circuit have good capability in linearity, resolution and stability. The image reconstruction algorithm is based on optimzation-revision regularization method. Experimental results show the algorithm to have advantages as regards the quality of reconstruction image and the reconstruction rate. |
