摘要
基于Pockels效应原理,分别对交直流混合强电场传感器中的电光传感单元和电场调制机构进行了设计与测试。对电光传感单元结构进行合理设计,选取并制备相关器件。搭建试验平台,试验结果表明电光传感单元输入输出具有良好的线性度,对电场波形的变化具有快速的响应且频率特性良好,其性能满足测量调制后电场波形的需求。利用电光传感单元和电场调制机构组建传感器,并测量了交直流混合强电场响应。
Based on the principle of the Pockels effect, the electro-optical sensing unit and the electric field modulation mechanism in the AC-DC hybrid strong electric field sensor are designed and tested. Reasonably design the structure of the electro-optical sensor unit, select and prepare related devices. The test platform was built, and the test results showed that the input and output of the electro-optical sensor unit had good linearity, had a fast response to the change of the electric field waveform, and had good frequency characteristics. Its performance met the needs of measuring the modulated electric field waveform. The electro-optical sensing unit and the electric field modulation mechanism are used to construct a sensor to measure the strong AC and DC electric field.
