瞬态电磁场测试的无源电光式传感器
-
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,可用于复杂电磁环境下或小空间内的脉冲电磁场测量。Abstract: 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, li near 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 wideband, passive, small size and being free from electromagnetic interference, and can be used for EMP measurement in small volum e.
