values. A high-speed capacitance measuring circuit converts the capacitance values to digital data and the data is sent via a wireless link to a host PC. To reconstruct permittivity images from the received data, two fast image reconstruction techniques (Linear Back Projection and Tikhonov regularization) are used. High-resolution images of a plastic rod, a plastic tube, the rod inside the tube and four rods together have been successfully produced. Tikhonov Regularization algorithm with an optimal regularization parameter produces better images than the LBP in this system.
