Abstract :
Electromagnetic tomography (EMT) is one kind of tomography based on electricity sensing principle. It can reconstruct spatiotemporal distributions of the electrical conductivity and magnetic permeability materials by detecting the boundary magnetic induction of the researched space. Sensor array of EMT system has the advantages of non-invasive, non-contacting and non-hazardous and has many potential applications in industrial fields. This paper presented the fundamental principle of EMT and studied the sensing field of sensor array using the Finite element (FEM) simulation. The magnetic induction distribution of the sensing field with this excitation model has been acquired. The influence of objects with different permeability, conductivity, and positions on the excitation sensing field was analyzed. The results were verified by image reconstruction experiment.
