Abstract
An Electrical Capacitive Tomography (ECT) sensor system for imaging heterogeneous dielectric material includes multiple ECT sensor heads, a portable, wireless ECT reader that interfaces with the ECT sensor heads. The ECT reader includes an efficient low computational cost fuzzy logic dielectric ECT image synthesizer. The fuzzy logic dielectric ECT image synthesizer can an independent processing chain for each pixel. Due to the low computation cost the fuzzy logic image synthesizer is able to produce video imagery of dynamic flows or reactions.
