摘要
干涉式光纤陀螺 ( IFOG)中光波偏振态的变化对输出信号的质量会产生很大的影响 ,本文从原理上分析了保偏和消偏这两种消除偏振误差的方法 。
Change of polarization state when optical wave in IFOG is propagated has gigantic effect for quality of deferent signal. This paper presents the principle of preserving polarization state and removing polarization state for removing polarization error. The depolarizer base on fiber ring is latestly proposed, which has very good performance and pratical value.
