    • PROBLEM TO BE SOLVED: To provide a low-cost and high-performance gyroscope using an optical frequency comb stimulated Brillouin scattering gyroscope, for navigation systems, precision point systems, and guidance systems.SOLUTION: A systems comprises a light source configured to produce a multiple-frequency light beam based on an optical frequency comb, and an optical fiber resonator. The multiple-frequency light beam propagates in a first direction within the optical fiber resonator on the basis of a generated optical frequency comb, and the multiple-frequency light beam generates stimulated Brillouin scattering on the basis of the optical frequency comb, and the stimulated Brillouin scattering generates a stimulated Brillouin scattering light beam to propagate in the optical fiber resonator in a second direction opposite to the first direction. The system also comprises: at least one servo that controls the frequencies of the optical frequency comb so that a plurality of component frequencies of the optical frequency comb are locked on resonance peaks of the optical fiber resonator in the first direction; and a mixer configured to determine a frequency difference between the stimulated Brillouin scattering light beam and the multiple-frequency light beam.
    • 要解决的问题:提供一种使用光学频率梳状刺激的布里渊散射陀螺仪的低成本和高性能的陀螺仪,用于导航系统,精密点系统和引导系统。解决方案:A系统包括被配置为产生 基于光频梳的多频光束和光纤谐振器。 多频光束基于所生成的光频梳在光纤谐振器内沿第一方向传播,并且多频光束基于光频梳而产生受激布里渊散射,并且被激发的布里渊 散射产生受激布里渊散射光束,在与第一方向相反的第二方向上在光纤谐振器中传播。 该系统还包括:控制光频梳的频率的至少一个伺服器,使得光频率梳的多个分量频率在第一方向上被锁定在光纤谐振器的谐振峰上; 以及配置为确定受激布里渊散射光束和多频光束之间的频率差的混合器。
