摘要：An Electromagnetic Tomography (EMT) prototype system based on integrated impedance analyzer is proposed and developed in this paper. In the prototype system the excitation signal generation and measurement signal demodulation are both realized by using an integrated impedance analyzer IC controlled by an embedded microcontroller. The sensor is constructed with a parallel excitation layer, which is realized with flexible circuit strips as current sources, and coil detector array. The sensor simulation and image reconstruction experimental results of the prototype EMT system are also introduced. The experimental image reconstructions show that the prototype system can locate the distributions of test objects. This work provides a solution that the EMT system can be developed as an embedded instrument to meet the requirement of industrial environment.
