摘　　要：本文设计了一种利用晶体的线性电光效应获取发射和接收两部分装置间相对转动的方位信息的光学系统。推导了出射的o光和e光的强度差与发射、接收两部分相对转角之间的关系,并对可能出现的误差进行了分析。The analysis of an optical system that is designed for obtaining the relative rotary movement azimuth information between the transmitter and the receiving settings is reported. By using the LiNbO3 crystal's linear electro-optic effect we have deduced the relationship between the intensity difference of the outgoing o ray and e ray and the relative rotary angles of the transmitter and the receiving settings. Some possible errors have also been analyzed.
