摘要
基于闭环光纤陀螺仪进行了标度因数的温度稳定性研究.建立了标度因数公式,分析了温度影响标度因数稳定性的主要原因,给出了相应参数的温度系数;利用闭环光纤陀螺样机进行了温度试验.试验结果表明:光纤陀螺仪标度因数的温度灵敏度由8.08×10-4/℃改变为1.70×10-5/℃.
Based on closed-loop fiber optical gyroscopes, research work on the temperature stability of the scale-factor has been performed. The mathematical expression of the scale-factor has been established. The mechanism of temperature influence on the stability of scale-factor was analyzed. The coefficient of some parameters was given. An experiment on the temperature stability of the scalefactor has been performed in closed-loop fiber optical gyroscopes. It can be seen from the experimental results that the temperature sensitivity of the scale-factor has been changed from 8.08×10-4/℃ to 1.70×10-5/℃
