提出并实现了一种采用高频庞德霍尔(PDH)调制的短纤度高精度光纤环形谐振器的谐振式微光陀螺。为了最大化解调曲线的斜率，对PDH调制的调制频率和指数进行了优化。在优化参数的基础上，RMOG谐振频率伺服环的锁定精度提高到0.178°/h，与低频调相相比提高了近两个数量级。
A resonant micro optic gyro (RMOG) equipped with a short and high-finesse fiber ring resonator employing the high-frequency Pound-Drever-Hall (PDH) modulation is proposed and demonstrated. The modulation frequency and index of the PDH modulation are optimized to maximize the slope of demodulation curve. Based on the optimum parameters, the lock-in accuracy of the resonant frequency servo loop in the RMOG is improved to 0.178°/h, which is almost improved by two orders of magnitude compared with that obtained for the low-frequency phase modulation.
