Phase measurement for electric field tomography.
The basic principles of electric field tomography (EFT) are briefly explained. EFT system numerical simulation results are given. The comparison of images reconstructed by systems with planar and round electrode arrays is presented. Some aspects of transmitting and measuring stages are discussed. The accuracy of the phase-sensitive demodulator, which is the key element of an EFT measuring system, is evaluated experimentally.
