We realize a transmissive single-beam-splitter resonator optic gyro based on a hollow-core photonic-crystal fiber (HCPCF), utilizing a micro-optical coupler formed by pairs of lenses and one filter, which is a new type of resonator fiber optic gyro based on the HCPCF (HC-RFOG). We build a mathematical model of the polarization noise based on the transfer function of this novel transmissive single-beam-splitter resonator. We construct a HC-RFOG and simulate and validate the effects of polarization noise on the gyro system. In addition, we apply an effective method to suppress the polarization noise and prove its efficacy through experiments. The bias stability of the gyro system is successfully improved from 25 °/h to 2 °/h, which indicates a remarkable advance of performance of HC-RFOG.
我们实现了一种基于空心光子晶体光纤（HCPCF）的透射式单光束分光器谐振器光学陀螺仪，利用由透镜对和一个滤波器形成的微光学耦合器，这是一种基于HCPCF的新型谐振器光纤陀螺仪（HC-RFOG）。我们基于这种新型透射式单光束分光器谐振器的传递函数建立了偏振噪声的数学模型。我们构建了一个HC-RFOG，并对偏振噪声对陀螺仪系统的影响进行了模拟和验证。此外，我们应用了一种有效的方法来抑制偏振噪声，并通过实验证明了其有效性。陀螺仪系统的偏置稳定性成功地从25°/h提高到了2°/h，这表明HC-RFOG的性能有了显著提升。
