| 摘 要： | 为了实现激光陀螺实时抖动解调，与陀螺输出信号同步采样抖动反馈信号，并设计算法将两个信号的抖动分量相位和幅度对准，然后执行抖动剥除运算。这种实时解调算法不仅计算量小，而且没有附加相位延迟。

| Abstract: | Introduced a real-time dither demodulating method for Ring Laser Gyro. The dither feedback signal must be sampled synchronously with the RLG readout signal, with a new algorithm for aligning phase and amplitude between the two signals, mainly a dither stripper. The algorithm can greatly reduce the calculating complexity without phase dely pulled in. |
