通过采用减低转速的办法测得的锁区值推算出的随机游走比用Allan方差方法拟合的随机游走要大很多.为了解释这一问题,建立了动态刻蚀光栅模型,与以往的研究不同,本文认为刻蚀光栅效应不只在驻波状态下发生,在行波状态下也会存在,而且与拍频频率呈现动态响应的关系.这种模型得出了锁区随着转速的降低而不断增大的结论,解释了长期以来困扰激光陀螺研究者的一些问题.
In order to explain this problem, a dynamic etching grating model is established, which is similar to the conventional In this paper, we consider that the etching grating effect not only occurs in the standing wave but also in the traveling wave, and also shows the dynamic response to the beat frequency. The model shows that the lock area decreases with the rotation speed The ever-growing conclusion explains some of the problems plaguing laser gyro researchers for a long time.
