Investigation of Electrical Resistance Tomography on Single Electrode Measuring Method

摘要

A new Data Acquisition Method (DAM), namely the single drive electrode method, used in Electrical Resistance Tomography (ERT) system is introduced in this paper. The ERT system based on the new DAM has been designed. The bi-directional pulse current used in this system has been analyzed. The experiments results and the reconstruction image are shown finally in order to testify the reliability of the new system and the feasibility of the new DAM.
