摘　　要：光纤环温度效应引起光纤双折射率变化,导致谐振式光纤陀螺中产生偏振波动噪声,影响陀螺零偏及标度因数。理论分析了光纤环温度变化对标度因数和零偏特性的影响;搭建了基于单路闭环谐振式光纤陀螺的静态模拟测试系统,测得动态检测范围为±169°/s,标度因数非线性度为0.235%;对谐振式光纤陀螺进行宽温度范围内全速率试验,测试标度因数及零偏温度特性曲线。结果表明:标度因数及零偏存在温度周期性;标度因数在一个周期内存在最低谷点,对应的零偏较大或达到最大值。Polarization fluctuation noise in the resonator fiber optic gyroscope arising from fiber birefringence variations caused by the temperature effect of the fiber ring affects the zero bias and scale factor of the resonator fiber optic gyroscope.The effect of the temperature variation for the fiber ring on the scale factor and zero bias was theoretically analyzed.The static simulation testing system based on a single closed-loop resonator fiber optic gyroscope was built.The test results show that the dynamic detection range is ± 169°/s,and the scale factor nonlinearity is0.235%.The experiment at the gyro full rate over a wide temperature range was carried out to test the temperature characteristics of the scale factor and zero bias.The results show that the scale factor and zero bias have the temperature periodicity;the scale factor has the lowest point in a cycle,where the zero bias is larger or reaches its maximum.
