摘要

多通道电场传感器用于电阻抗和电容层析成像应用。在只能容纳单侧接入的情况下，使用边缘电场传感器(FEF)传感器。属!本文讨论了多通道边缘电场传感器的设计原理。分析了FEF传感器的穿透深度、信号强度、测量灵敏度和成像分辨率等性能指标。并对设计参数对传感器性能的影响进行了评价。本文这一部分描述的定性设计原则为本文第二部分将要介绍的基于仿真的设计优化过程提供了直观的指导。

Design of multichannel fringing electric field sensors for imaging. Part I. General design principles

Multichannel electric field sensors are used for electrical impedance and capacitance tomography applications. In cases where only one-sided access can be accommodated, fringing electric field sensors (FEF) sensors are used. The genera! design principles of multichannel fringing electric field sensors are discussed in This work. Analysis of the figures of merit of FEF sensors, such as penetration depth, signal strength, measurement sensitivity, and imaging resolution, are presented. The effects of design parameters on sensor performance are also evaluated. The qualitative design principles described in this part of the paper provide intuitive guidelines for the simulation-based design optimization procedure to be presented in the second part of the paper.
