摘要
从提高灵敏度角度出发,理论上分析了无电极电光电场传感器电极长度与灵敏度和带宽的关系。通过比较不同结构的传输函数,验证平衡检测方式的可行性,最后选取使用平衡检测的三端口结构作为实验器件结构,从而为器件制作的可行性方案从理论上作了验证。
Proceeding from the sensitivity improvement,the relation between the electrode length and the sensitivity/bandwidth of no-electrode electrical field sensor is analyzed. By comparing the transmission function of different structures and verifying the feasibility of balanced detection scheme, the 3-port structure using balanced detection is chosen for the coming generation sensors.
