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。 Based on the Hooke ’s law and the catastrophic effect, the mathematic model of non - reciprocal phase error of Saintec fiber ring under the impact of mechanical stress was established. The effects of Young’ s modulus of the binder on Sainc fiber ring were discussed. The effects of the Young’s modulus of the fiber binder on the error of the Sonar fiber interferometer were verified by simulation and experiments. The results show that the larger the Young’s modulus of the binder, the more stable the system performance.
