从理论上分析了光纤陀螺敏感环的热致非互易相位噪声, 建立了光纤环温度分布模型。 针对四种通常的光纤敏感环绕制方法(ZYL, SYM, DIP, QUA), 对于由外界环境温度变动所引起的光纤陀螺零位漂移进行了数值模拟与比较, 并给出了对应于外界环境温度变化过程中的光纤陀螺零位漂移补偿方案。

the characteristic of thermal induced non-reciprocal phase noise was analyzed theoretically, and the temperature distribution model was derived for the fiber sensing coil. The zero point drift of the fiber optic gyros (FOG) induced by outside temperature fluctuation was simulated numerically and compared with the four types of fiber sensing coil manufacture methods (ZYL, SYM, DIP, QUA). The related zero point drift compensated method was proposed.
