受激布里渊散射光纤陀螺中光纤光源的阈值光功率研究

Study on Threshold Power of the Fiber Source for the Stimulated Brillouin Scattering Fiber Optic Gyros (SBS-FOG)

从非线性受激布里渊散射产生机理出发 ,研究了受激布里渊散射光纤陀螺 (SBS- FOG)中光纤光源的阈值光功率与光源谱宽及保偏光纤敏感环参数之间的函数关系 ,为进一步研究这种光纤光源的构造以及建立受激布里渊散射光纤陀螺系统打下了理论基础。

In this paper, the relationship of the threshold power of the fiber source as a function of spectral width of this fiber source and parameters of the polarization maintaining fiber sensing coil was studied based on non linear stimulated Brillouin scattering theory for the stimulated Brillouin scattering fiber optic gyros (SBS FOG), which established theoretical foundation for investigating such fiber source conformation and constructing the system of the SBS FOG.
