电容耦合电阻层析成像传感器结构优化设计研究
Optimum Design for Capacitively Coupled Electrical Resistance Tomography Sensor Configuration
摘要
Abstract
The optimization for sensor structure of capacitively coupled electrical resistance tomography ( CCERT) is presented. The model of the 12-electrode sensor of CCERT has been established by finite element simulation software firstly, and sensitivity field has been calculated for the reconstruction of image. Then the finite element model is verified by comparing the simulation data and reconstructed image with that of experiment respectively. The result shows that the model is reasonable. The effect on the measurement data is studied by simulation for two different models of sensor. Finally, the optimum size of the screen of CCERT sensor is proposed with the minimum influence on the measurements based on the final sensor model discussed previously. The study can provide useful instruction for the design of CCERT sensor.关键词
