| 摘 要： | 光纤环是光纤陀螺中的核心部件。光纤环所处的环境因素，如温度、应力引起的非互易性相位噪声，制约了光纤陀螺向高精度、实用化的发展。通过有限差分法，对光纤环的Shupe效应作了研究，对四极子光纤环在非稳态传热的过程中的温度场进行数值求解，分析了光纤环在试验提供的温度环境下的温度零漂。提出了光纤环交叉子绕制方案。

| Abstract: | Fiber optical ring is the core parts of the interferometric fiber optical gyro. The external circumstance such as temperature and stress can induce nonreciprocal phase noise, which restricts the developing of high precision gyro. The quadrupolar ring's temperature field is studied numerically by finite difference method, its null drift is analyzed at given temperature circumitance. The cross winding technique is proposed, which is good for weakening the null drift induced by temperature. |
