光纤陀螺仪零漂信号的Allan方差分析

Allan variance analyse of the drift of the fiber-optic gyroscope

介绍了光纤陀螺零漂实验的设备环境,硬件和软件的构成及数据采集过程。在测得光纤陀螺零漂信号的基础上,运用Allan方差理论对陀螺信号进行定量的分析,得到了光纤陀螺5个误差源系数的大小,并根据误差源的产生机理,找到了光纤陀螺硬件存在误差的部分,提出了光纤陀螺的改进方案。

The equipment and environment of fiber of gyroscope (FOG) zero-drift experiment are introduced. The hardware and software of the equipment is designed to collect the signal of FOG. The zero-drift signal is analyzed to get five coefficients of error source, which bases on Allan variance theory. The error parts in hardware are found. The scheme to improve the performance of FOG is proposed.
