These techniques provide important information on steel condition within a reinforced concrete structure in a swift manner without breaking the concrete structure. Most of the existing systems only focus on the x-y plane scanning while the use of volumetric imaging to generate a cross-section and three-dimensional (3D) image of the concrete structure is relatively very rare. This volumetric imaging scheme is suitable for pillar structure imaging as the whole pillar structure can be viewed without any overlapping image. This thesis focuses on the design and development of a non-invasive and non-intrusive magnetic induction tomography system that emphasises on steel imaging in a pillar concrete structure. The developed system employs eight transmitters and eight receivers that are located in aluminium panels, with a region of interest of 280 mm diameter. The system that has been developed consists of several innovations in the electronic circuitry design that is able to improve circuit protection and noise reduction. A series of experiments and analyses for both static and dynamic samples have been carried out to evaluate the performance of the system in several medium conditions based on cross sections and 3D images. The application in reinforced concrete pillar structure imaging has proven that the proposed system is capable to detect and reconstructs of the steel structure image inside a concrete with a minimum resolution of 1.25 inch (3.175 cm) in diameter and a steel break with the gap size of 1.00 cm. The limitations of the developed system are that only cylindrical shape samples have been considered whilst in dynamic measurement, only single sample can be used at each imaging session atiff UTM 251 p.
