Effect of Shock on Sagnac Fiber Interferometer Performance
摘要
基于胡克定律和弹光效应, 建立了冲击机械应力作用下萨奈克光纤环非互易性相位误差产生的数学模型, 讨论了黏结剂的杨氏模量对萨奈克光纤环的影响, 通过仿真和实验验证了光纤黏结剂杨氏模量的大小对萨奈克光纤干涉仪误差的影响。结果表明黏结剂杨氏模量越大, 系统性能越稳定。
Abstract
The mathematical model of the nonreciprocity phase error generation of Sagnac fiber coil under the shock mechanical stress is established based on Hooke′s law and the elastic-optic effect theory. The influence of Young′s modulus of adhesive on the Sagnac fiber coil is discussed. The influence of Young′s modulus of the fiber adhesive on the Sagnac fiber interferometer error is verified by simulation and experiment. The results show that the higher the Young′s modulus of the adhesive is, the more stable the system is.
