Abstract: The paper describes the hardware development and performance of the Dual Modality Tomography (DMT) system. DMT consists of optical and capacitance sensors. The optical sensors consist of 16 LEDs and 16 photodiodes. The Electrical Capacitance Tomography (ECT) electrode design use eight electrode plates as the detecting sensor. The digital timing and the control unit have been developing in order to control the light projection of optical emitters, switching the capacitance electrodes and to synchronize the operation of data acquisition. As a result, the developed system is able to provide a maximum 529 set data per second received from the signal conditioning circuit to the computer.

 

Keywords: electrical capacitance tomography; optical tomography; dual mode tomography (DMT); forward modelling; signal conditioning circuit
