This article presents investigation of 3-D electrical capacitance tomography (ECT) sensors with different excitation strategies, including dual-electrode excitation in the same plane, in adjacent plane, in planes separated by one plane or two planes, and in the adjacent position or opposite position in the same or different planes. The results show that a 3-D ECT sensor with dual-electrode excitation in the opposite position provides higher mean capacitance and lower standard deviation than in the adjacent position. Dual-electrode excitation in different planes can increase the capacitance signal and decrease the dynamic range of capacitance measurements, and thus, decrease random errors and improve the quality of 3-D reconstructed images. A 3-D ECT sensor with dual-electrode excitation in planes separated by one plane and opposite position can provide small measurement uncertainty and high image quality.

3D 电容层析成像传感器的激励策略


本文介绍了采用不同激励策略的 3-D 电容层析成像 (ECT) 传感器的研究，包括同一平面、相邻平面、由一个平面或两个平面分隔的平面以及相邻位置或相邻位置的双电极激励。在同一平面或不同平面上的相对位置。结果表明，相对位置采用双电极激励的 3-D ECT 传感器比相邻位置提供更高的平均电容和更低的标准偏差。不同平面的双电极激励可以增加电容信号并降低电容测量的动态范围，从而减少随机误差并提高 3D 重建图像的质量。一种 3-D ECT 传感器，在由一个平面分隔且相对位置的平面中采用双电极激励，可以提供较小的测量不确定度和较高的图像质量。
