摘　　要：为了解决用BSO晶体制作闪电电场传感器中旋光效应对电光效应的影响问题,需要从理论上对光的传播方程进行研究。通过对BSO晶体中电光效应和旋光效应对光的偏振态影响的研究,推导了处于外加电场中的BSO晶体中光的传播方程的表达式,以及透过光强的表达式研究了BSO晶体旋光性对电光效应的影响,通过理论分析提出了消除旋光效应的方法。给出了一种基于BSO晶体电光效应的闪电电场传感器的制作方法及测量系统框图,并通过仿真从理论证明了BSO晶体作为闪电电场传感器材料的可行性。In order to solve the impact problem of rotation effect on electro-optical effect for lightning electric field sensor de- sign using BSO crystal, to study the theory of light propagation equations is needed. Based on the study of effect on the state of po- larization of light by BSO crystal＇ s electro-optic effect and rotation effect, this paper derived the optical transmission equation of BSO crystal in the external electric field, and the intensity of the transmitted light. It studied the effect of rotation effect on electro- optical effect of BSO crystal, proposed method to eliminate the rotation effect by theoretical analysis. This paper presented a produc- tion method and the measurement system block diagram of the lightning electric field sensor which based on the electro-optic effect of BSO crystal, and proved the feasibility of BSO crystal as lightning electric field sensor material by the analo~ simulation.
