In the past, electrical capacitance tomography (ECT) with circular sensors has been extensively investigated. For some industrial applications such as circulating fluidised beds, square sensors are required. Research into this specific area has been carried out at UMIST for the first time. To generate sensitivity maps, the Laplace equation is solved using a finite difference method (FDM). Both the linear back-projection (LBP) and an LBP-based iterative algorithm have been implemented for image reconstruction. Experimental results are very promising.
