文章提出了一种在开环去偏光纤陀螺基础上实现闭环解调的方案，并分析了反馈信号的各项参数的变化对陀螺输出信号的影响。在保持零偏稳定性好的情况下，在±300°／s转速范围内实现了较低的标度因数非线性度。
In this paper, a scheme of closed-loop demodulation based on open-loop depolarized fiber gyro is proposed, and the influence of various parameters of feedback signal on gyro output signal is analyzed. With good bias stability, a lower scale factor non-linearity is achieved over a ± 300 ° / s speed range.
