固胶对保偏光纤环的影响

阐述了固胶对光纤环及光纤陀螺两个重要性能参数——温度性能和振动性能的作用和影响,针对某项目对光纤陀螺实际要求的条件进行了陀螺的全方面试验,并分析试验结果.试验和分析结果表明,固胶对光纤环和光纤陀螺的影响是由涂胶工艺不当带来的,涂胶量及涂胶的均匀度是产生影响的两个主要因素,胶的温度性能及自身固化后状态对光纤环性能也会产生影响.得出结论:固胶工艺或固胶方式、方法对光纤环的性能有极大的影响,特别是对光纤环在温度变化时的影响表现更为明显,另外,固胶对光纤环的影响,还表现在胶固化后的状态. 

Effect caused by coating adhesive on polarization-maintaining fiber coil

The action and effect on the two important performance parameters such as temperature and vibration of the fiber ring and fiber optical gyroscope(FOG) were expatiated.In allusion to the factual conditions of the FOG of some item,all aspects of experiments were done and the experiment results were analyzed.The experiment and analysis results show that the effect caused by coating adhesive to the fiber ring and FOG is brought due to the unsuitable coating adhesive.The amount and uniformity of coating adhesive are the two main facts of the effect.The temperature performance and the state after solidification of the adhesive can bring effect.Conclusions are gained: it is effected greatly by coating adhesive technics and methods or mode;it becomes more clearer with the temperature changing especially;in addition,it is existing after the adhesive curdles.
