摘要
光纤环是光纤陀螺仪中的核心部件。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,对陀螺仪精度的影响不容忽视,并且成为光纤陀螺仪工程化的瓶颈。该文通过有限差分法,对四极子光纤环在非稳态传热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。提出光纤环尾纤补偿方案。
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.In this paper.we studied the quadrupolar ring′s temperature field by finite difference method and simulated the ring′s null drift in especially gived dircumstance.We bring up the fiberringtailcompensation method.which is good for weakening the null drift induced by temperature.
