采用抖动剥除算法能够使二频机抖陀螺的输出信号达到零延时。现有的抖动剥除算法无一例外地采用外部参考信号进行剥除运算，外部参考信号的获取会增加系统的复杂度。为了使抖动剥除更加容易实现，提出了一种新的基于自锁相的抖动剥除方法，用陀螺本身来获取抖动信号，不再需要外部参考信号。这种方法硬件结构简单，同时实验结果证明其输出结果不差于采用外部参考的方法。该方法使二频机抖陀螺可以很方便地应用于实时控制领域。

Zero time delay can be achieved by using dither stripping method for the readout signal processing of mechanical dithered ring laser gyro (MDRLG). An external dither pickoff reference signal is needed for all existing dither stripping apparatuses. The obtaining of the dither reference will make the application system more complex, and the system will be less stable. A new dither stripping method is developed, in which external reference signal is needed no more; instead the reference signal is generated by the gyro itself. The circuit is simplified by using this method; meanwhile experimental results show that this method can achieve better output results than those of the method using external reference. This method makes the MDRLG easier to be used in the applications of fast control and tracking.
