| 摘 要： | 为了研究谐振腔形状变化对激光陀螺中背向散射的影响,基于矢量叠加理论,分析了激光陀螺背向散射源及其对总的背向散射的影响.根据背向散射对顺逆时针光的耦合作用,推导出了总的背向散射系数与顺逆时针旋转光光强的关系式.基于这一关系,设计实验,通过施加电压使谐振腔反射镜到不同位置来改变光腔形状变化,同时测量光强交流量的振幅,得到了总的背向散射系数的变化曲线.通过与仿真结果对比,验证了背向散射的矢量叠加理论. |

| Abstract: | Backscattering sources and their influence on total backscattering in ring laser gyroscope was analyzed based on vector superposition principle.According to the coupling effect of backscattering on counterclockwise and clockwise beam,the relationship between total backscattering coefficient and light intensity of oppositely directed traveling waves was derived.Based on this relationship,the curve of backscattering was obtained through pushing and pulling mirrors to different places to change the shape of re... |
