چکیده

Electrical capacitance tomography (ECT) technology has the softfield nature and the ill-posed problems. To solve the problem of low imaging quality by standard Tikhonov regularization, a wavelet fusion algorithm based on Tikhonov regularization is proposed in this paper. Firstly, Tikhonov regularization method is used to solve ill-posed characteristic of system inverse problem, then the initial image is decomposed and fused by using wavelet transform. The simulation results show that this method can not only improve the image reconstructed by standard Tikhonov regularization, but also provides a new idea to ECT image reconstruction.

Fusion Research of Electrical Tomography with Other Sensors for Two-phase Flow Measurement

The two-phase flow widely exists in the nature and industrial processes. The measurement of two-phase flows, including gas/solids, gas/liquid and liquid/liquid flows, is still challenging. Fusions of electrical tomography with conventional sensors provide possibilities to improve two-phase flow accurate measurement. In this paper, fusions of (1) electrical resistance tomography (ERT) with elect...
