Development and application of wide band electro optic measurement system for pulsed E-field

介绍了一种宽频带电光式脉冲电场测量系统（ＰＥＭＳ－ １），该系统动态范围约６０ｄＢ，频率响应为０．１Ｈｚ～７００ＭＨｚ，具有抗电磁干扰能力强、探头部分无源化、体积小等优点，可用于传统测试手段难于实现的复杂电磁环境下或小空间内的瞬变电场测量。给出了系统组成及分析，对频率响应与线性测量范围进行了实验研究，提出了一种无标准场时有效进行幅值标定的方法。最后，在两种脉冲电场环境中进行了测试应用。

This paper describes a photonic based pulsed E field measurement system. The system is operable from 0.1Hz to beyond 700MHz, and has the linear dynamic range of at least 60dB. The small probe size and all dielectric fiber optic cabling of the passive electro optic probe allows for non intrusive pulsed E field measurement in small enclosure or complicated electromagnetic environments. The system design, analysis and one method of calibration when absent of uniform field were presented. Applications were done in the measurement of fields in air that produced by bounded wave EMP simulator and free field radiation EMP simulator, respectively.
