摘要
介绍了一种用于瞬态电磁场测试的无源电光式传感器及其应用系统，其信号输入动态范围约为６０ｄＢ，频率响应范围为１０ｋＨｚ～７００ＭＨｚ，这种探头部分无源化的传感器具有抗电磁干扰能力强、体积小等优点。
A small passive electro optic EMP sensor over frequency range from 10kHz to 700MHz has been developed. The sensor's operation properties, such as the frequency response, linear dynamic range, sensitivity, optical power dependence, dipole element length dependence and impulse response,were measured, which agreed with the calculated results. It has the characteristics of wide band, passive, small size and being free from electromagnetic interference, and can be used for EMP measurement in small volume.
