基于电光晶体的泡克尔斯效应和磁光玻璃的法拉第效应，提出一种新颖的光学电功率传感系统。该系统主要将电光晶体与磁光玻璃串联使用，可以直接获取电功率传感信号。研究了该传感系统的传感原理，并分别对纯电阻性和感性负载进行交流电功率传感实验，其非线性误差分别低于1．3％和1．4％。
Based on the Foleck effect of electro-optic crystal and the Faraday effect of magneto-optic glass, a novel optical power sensing system is proposed. The system mainly uses electro-optic crystal and magneto-optical glass in series, and can directly obtain the electric power sensing signal. The sensing principle of this sensing system was studied. The AC power sensing experiments of pure resistive and inductive loads were carried out respectively, and the nonlinear errors were less than 1.3% and 1.4% respectively.
