摘要
建立了光纤环与光纤陀螺角速度误差及其零偏稳定性的关系模型,设计和完成了光纤环透射光谱及其长度在全温范围内的温度实验,分析了光纤环透射光谱及其长度的温度特性,仿真了光纤环透射光谱和长度的全温变化引起的光纤陀螺角速度误差和零偏稳定性。结果表明：全温范围内,光纤环透射光谱的功率、平均波长和光纤环长度变化分别为1. 32%、13. 9 ppm和846 ppm,它们的变化引起的角速度误差和零偏稳定性分别为6. 01×10^-2°/h和4. 15×10^-2°/h;光纤环的温度特性对高精度光纤陀螺的温度性能造成了严重的影响。
The model of the relationship betweeen some parameters of fiber coil and rotational angular velocity errors and bias stability of fiber optic gyroscope（ FOG） was established. The temperature experiments of the transmission spectra and length of the fiber coil were designed and completed,and their temperature characteristics were analyzed.The rotational angular velocity errors and bias stability of FOG caused by the changes of the transmission spectra and length of the fiber coil were simulated. The results show that the maximal changes from-40℃ to 60℃ of the power,mean wavelength of the transmission spectra and length of the fiber coil are 1. 32×10^-4/℃,1. 39×10^-7/℃ and 8. 46×10^-6/℃,respectively,and the maximal rotational angular velocity errors and bias stability of FOG caused by these changes are 5. 79×10^-2°/h and 4. 09 × 10^-2°/h,respectively. The temperature stability of the fiber coil influences the temperature performance of high-precision FOG seriously.
