Design method of ERT-ECT bimodal composite electrode

The invention relates to a design method of an ERT-ECT bimodal composite electrode, and belongs to the field of electrical tomography. According to the method, an ERT-ECT bimodal composite imaging system is defined, and ERT and ECT mathematical models are established. According to the characteristics of capacitance and resistance measuring electrodes, a circular resistance measuring electrode is placed in an annular capacitance measuring electrode and is isolated from the annular capacitance measuring electrode by an insulating ring, so that the area of the resistance measuring electrode is reduced, the area of the capacitance measuring electrode is increased, and the utilization rate of the edge area of a measured field domain is improved under the condition of ensuring the accuracy of a resistance measuring result; and meanwhile, the electrodes adopt an integrated design mode, so that hardware of a measurement system is easy to disassemble and assemble. 本发明涉及一种ERT-ECT双模态复合电极设计方法，属于电学层析成像领域。该方法明确ERT-ECT双模态复合
