机械抖动激光陀螺过锁区分析与处理

利用计算机仿真分析了机械抖动激光陀螺过锁区的各种可能波形及原有鉴相方法相应的鉴相结果,从中发现了原鉴相方法存在的问题。据此提出了一种平衡处理各种进出锁区波形的新鉴相并与原鉴相方法在陀螺上进行了相对实验。实验表明新鉴相方法得到了数据正确,因此能用于机械抖动激光陀螺过锁区处理。

Analysis and Process of Lock-in in Mechanically Dithered Ring Laser Gyro

Waveform inlock-in area of mechanically dithered ring laser gyro (RLG) and output of the old phasedemodulator were analyzed by computer simulation.The error of the old phase demodulatorwas found and a new method to overcome this error was introduced.Tests show that datum gotthrough the new method are right and the method can be used for treating with signals fromdithered RLG.
