摘　　要：利用激光、电光学效应 ,克尔效应 (二次光学效应 )测量电场的分布 ,可以在几乎不改变被测电场分布的情况下 ,测出克尔效应物质所在点电场强度。据此研制的以硝基苯液体代替 Pockels晶体的激光—克尔效应高压电场测量系统 ,可用于工频冲击和直流场强的测量。Using laser, electro-optic effect and Kerr effect to measure electric field distribution, The electric field intensity where the Kerr effect material lies can be measured without changing the measured electric field distribution. The system with nitrobenzene(similar with effect of Pockels) developed in this paper can be used to measure power frequency, impulse electric field and DC electric field intensity.
