摘要
介绍了基于马赫–曾德尔干涉原理和萨格奈克(Sagnac)效应的马赫–曾德尔型光纤陀螺(MZ 型光纤陀螺)的工作原理。在此基础上，分析了两光纤臂长差对光纤陀螺零位漂移和温度稳定性的影响，指出臂 长差的存在是影响MZ型光纤陀螺系统稳定性和灵敏度的最主要因素。
Abstract
The operation principle of a Mach-Zehnder fiber optic gyroscope (MZ-FOG) based on Mach-Zehnder interferometric principle and Sagnac effect is presented. The influence of fiber length difference on the zero drift and thermal stability of the fiber optic gyroscope is analyzed. It is pointed out that the fiber length difference is the main factor to affect the stability and sensitivity of the fiber optic gyroscope system.
