摘　　要：分析了腔平移镜这一引起激光陀螺光路变动的主要因素,旨在揭示腔平移镜影响激光陀螺内部光路的机理及其影响的大小。通过分析计算得出,腔平移镜歪扭引起激光陀螺内部光束通过光栏中心位置时产生的横向位移相当于光栏半径10%~20%的变化。通过搭建光路测试系统,验证了腔平移镜歪扭的变化主要造成了激光陀螺内部光束通过光栏中心位置的变化这一结论,分析了这一变化对激光陀螺性能影响的机理。The mirror transducer assembly causing light path variation of ring laser gyro is analyzed.This analysis reveals how the action mechanism of the mirror transducer assembly influences light path in ring laser gyro and to what extent it may have.The calculated results indicate that mirror tilt can induce a light path shift of about 10～20% aperture diameter at the aperture transverse section.A test system is built to verify that it is the tilt of mirror transducer assembly which causes the light path variation at the aperture.At last,the impact of the action mechanism of light path variation on ring laser gyro performance is discussed.
