提出了一种基于双法拉第转子系统的谐振微球陀螺，该谐振微球陀螺具有插入损耗小、不破坏陀螺系统互易性的特点。采用回波抑制结构和正交极化方法可以有效地抑制后向散射噪声和极化误差，使其降低到系统灵敏度极限以下。优化后的后向散射噪声和偏振噪声使谐振不对称率从34.2%下降到2.9%，大大提高了系统的偏置稳定性和标度因数线性度。此外，基于双法拉第转子系统的最佳参数，在使用直径为1 mm、Q为7.2 × 10 ~（6）的微球谐振器的谐振微球陀螺中，在1000 s内积分时间为10 s时，零偏稳定度为0.04度/s。(C)2016美国光学学会
The resonant microsphere gyroscope is proposed based on a double Faraday rotator system for the resonant microsphere gyroscope (RMSG) that is characterized by low insertion losses and does not destroy the reciprocity of the gyroscope system. Use of the echo suppression structure and the orthogonal polarization method can effectively inhibit both the backscattering noise and the polarization error, and reduce them below the system sensitivity limit. The resonance asymmetry rate dropped from 34.2% to 2.9% after optimization of the backscattering noise and the polarization noise, which greatly improved the bias stability and the scale factor linearity of the proposed system. Additionally, based on the optimum parameters for the double Faraday rotator system, a bias stability of 0.04 degrees/s has been established for an integration time of 10 s in 1000 s in a resonator microsphere gyroscope using a microsphere resonator with a diameter of 1 mm and a Q of 7.2 x 10(6).
