电容层析成像系统中电容传感器参数优化设计

电容层析成像系统中，图像重建的质量主要依赖于电容敏感场分布的均匀性，这一性质又由传感器的几何和材料参数决定，因此传感器的设计尤为重要．根据敏感场颁上的均匀性，灵敏程度和电容测量技术，确定了传感器的优化参数；在多因素轮换的基础上，采用正交设计法进行电容传感器参数的计算机辅助设计，从而快速地获得一组最优参数．在实际应用中，概据此优化参数制造的电容传感器获得了较为理想的重建图像．

Parameter Optimization of Capacitance Transducer of Electrical Capacitance Tomography System

Because the quality of image reconstruction of electrical capacitance tomography system mainly relies on the equality of the capacitance sensitivity field, which depends on the geometrical and material parameters of capacitance transducer, it is vital to design the capacitance transducer. According to the equality of the capacitance sensitivity field, sensitivity and the measurement of capacitance, we confirm the optimizing parameter. On the basis of multi-ingredient, we adopt orthogonal designing method to design the parameters of capacitance transducer, and achieve a set of optimizing parameters quickly. In the applications, the capacitance transducer made by the set of optimizing parameters can get the ideal reconstruction image.
