| 摘 要： | 本文从非线性的受激布里渊散射理论出发,研究了受激布里渊散射光纤陀螺（ＳＢＳ－ＦＯＧ）中的受激布里渊散射效应产生机理,得出了阈值光功率与光纤敏感环各参数之间的函数关系,并用针对两种光纤芯折射率分布情况,对于所导出的上述函数关系进行了数值模拟和图形表示,从而为合理选取这种光纤陀螺的参数提供了理论依据。

| Abstract: | The mechanismof the stimulated Brillouin scattering was investigatged for the stimulated Brillouinscattering fiber optic gyros (SBS-FOG) by using non-linear theory,and the functionalrelation between threshold power of the fiber source and paramaters of the fiber sensingcoil was educed.This relation was numerically simulated and graphically expressed for twotype refractive index distribution,which provided theoretical basis for exactly choosingthe parameters of the SBS-FOG. |
