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。
Fiber ring is a core component in fiber optic gyroscopes. The environmental factors on the optical fiber ring, such as non-reciprocal phase noise caused by temperature and stress, constrain the development of the optical fiber gyro to high precision and practicality. The finite difference method is used to study the Shupe effect of the fiber ring. The temperature field during the unsteady heat transfer of the quadrupole fiber ring is numerically solved. The temperature of the fiber ring in the temperature environment Zero drift. Proposed a fiber ring cross-sub-winding scheme.
