摘　　要：文中提出了一种基于泡克耳斯效应的集成光学电压传感器测量直流电压的研究方案,光纤光路结构采用熊猫型保偏光纤与低偏光纤相结合以提高系统光路的互易性,理论上利用琼斯矩阵推导了入射光光路数学传输模型,得出干涉光强与干涉信号的关系表达式。针对该光学电压传感器设计方案,搭建了实验平台并对系统进行了0~15 V直流实验,实验结果表明该传感器输入电压与数字输出曲线之间具有良好的线性关系,最大非线性误差为0.2%,可初步证明该传感器互易光路的可行性。A research scheme for measuring DC voltage with integrated optical voltage sensor based on Pockels effect was proposed.Panda type polarization maintaining fiber and low polarization fiber were combined to improve the system s light path interoperability.Theoretically,Jones matrix was used to derive the mathematical transmission model of incident light path,and the relation expression between the intensity of interference light and the interference signal was obtained.According to the design scheme of the optical voltage sensor,an experimental platform was built for the system and 0~15 V DC experiment was carried out.The experimental results show that there is a good linear relationship between the input voltage and the output curve of the sensor,and the maximum nonlinear error is 0.2%,which can preliminarily prove the feasibility of the sensor s reciprocal light path.
