Abstract

Electromagnetic tomography method works by utilizing magnetic field induced by coils that are given an electric current. An object with certain conductivity property interferes the magnetic field which will be sensed by the sensor in the form of voltage difference. Experiment using iron as an object has been conducted. In addition, parameters given are distance between transmitter and receiver coil, and frequency of transmitter signal. The result shows that conductive material gives significant voltage difference, which ranges between 0 - 0.072 V. The optimal transmitter-receiver coil distance is the shortest, while the optimal transmitter signal frequency is at 5MHz and 9MHz. Based on the optimum parameters gained, multi-channel magnetic induction tomography (MIT) sensor is designed. It contains four transmitter coils and four receiver coils. They are arranged in circle, which each transmitter and receiver pairs are in opposite location. The sensor proved to be able to sense voltage difference induced by an object. Samples of imaging are also successfully provided accordingly.
