闭环光纤陀螺量程扩展方法研究

Research on Range Extension Method of Closed-loop Fiber-optic Gyroscope

从闭环光纤陀螺工作原理出发,分别对跨条纹调制法和单级干涉条纹量程扩展法两种扩展闭环光纤陀螺量程的方法进行了分析。结果表明基于单级干涉条纹的量程扩展方法在工程上更加简单易行,基本不用对算法和硬件进行改动,具有很高的工程实用价值。

In this paper, it makes an analysis on two range extension methods of closed-loop fiber-optic gyroscope： cross-strip modulation method and single-stage interference strip based range extension method, respectively, according to the operation principle of closed-loop fiber-optic gyroscope. The results show that the single-stage interference strip based range extension method is easier to be implemented in engineering. It does not need to make a modification in al- gorithm and hardware, and also has great value in engineering.
