| 摘 要： | 谐振式微光学陀螺(RMOG) 是通过检测基于Sagnac效应产生的谐振频率差来测量旋转角速度的一种新型光学传感器。针对RMOG检测电路信号质量差、功能单一，无法兼容不同光路结构的问题，提出了基于虚拟仪器的RMOG数字控制方案，利用Labview编程的灵活性，完成了锁频环路的设计并进行了实验验证，实验结果表明1h陀螺锁频精度为0.03 °/s。1 h的输出精度为1.4 °/s。

| Abstract: | As one of the new optical sensing devices, Resonator Mcro-optic Gyro(RMOG) measures the rotation velocity through the resonance frequency difference based on the optical Sagnac effect. Compared with RMOG detection circuit specialized, disabled signals and no compatibility with different light path, the RMOG digital control system based on virtual instrument is presented. The frequency of fiber laser is locked by models combined together in the virtual instrument with the flexibility of Labview. The frequency locking precision is 0.03°/s over 1hour, and the bias stability is 1.4°/s with integration time of 10s over 1hour are obtained. |
