摘要
为解决常用场磨式大气电场仪体积大、机械磨损严重、易受电磁干扰、测量带宽窄等问题,在研究分析Pockels效应原理的基础上,提出应用Pockels效应来测量大气电场的方法。对晶体、光源的选择及传感器设计中出现的问题进行了分析,设计了一种基于Pockels效应原理的脉冲电场传感器,该传感系统包括稳定高效的光源、Pockels晶体探头、数据采集及处理电路。通过模拟仿真,说明了这种测量方法是可行的,为进一步研制大气电场测量传感器,提高其性能提供了理论依据。
In order to solve some problems of the common atmospheric electric field mill, such as bulk mass, serious abrasion, electromagnetic interference and narrow bandwidth, this paper advanced a new way to measure atmospheric electric field which is based on the research of Pockels effect, analyzed the choice problem of crystal and light source, and others which appeared during the course of design this sensor, and designed a pulse electric field sensor which was based on Pockels effect. This system consist of stable and high-efficiency light source, Pockels detector, data acquisition and processing circuit. According to the analog simulation, this method of measuring atmospheric electric field is workable, in this way it afford a basis for further design of this atmospheric electric field sensor and improving it' s performance.
