中文摘要：
介绍了一种在强电磁场环境中用于传输脉冲信号的宽带模拟量光纤传输系统。通过采用场效应管做前级放大与光电器件的非线性预校正，且提高级问RC耦合时间常数。该系统动态范围大，非线性失真小，带宽达到1Hz～150MHz，调整输入电路并配合天线能测量脉冲磁场或脉冲电场。给出了脉冲电磁场测量的耦合电路和测试实例。测试结果表明该系统很适用于宽带脉冲电磁场的测量。
英文摘要：
A fiber optic analogue transmission system for pulse signal in strong electromagnetic is introduced. By correcting the photoelectric cell＇s nonlinearity in advancer and by increasing the RC coupling time constant the system has wide dynamic range, little nonlinear distortion and wide pass band from 1 Hz to 150 MHz. By adjusting the input circuit along with an antenna the system can be used to measure pulse magnetic field or electric field. Design methods for the pulse electromagnetic field coupling circuits and measurement examples are presented. The examples show that the system is suitable for measuring wide band pulse electromagnetic field.
