| 摘 要： | 在光纤Bragg光栅传感原理的基础上,从理论上着重研究了由弹光效应引起的轴向应变灵敏度和径向应变灵敏度,并分别进行了轴向应变与径向应变灵敏度和轴向应力与径向应力灵敏度的仿真,仿真结果与理论分析相符。另外,对于动态轴向应变的情况,也给出了波长漂移随时间变化的仿真结果。

| Abstract: | In this paper,the axial strain sensitive and radial strain sensitive caused by strain-optic effect is mainly studied in theory on the basis of the principles of Fiber Bragg Grating sensor with the simulation of axial strain and radial strain sensitive as well as the axial stress and radial stress sensitive,and the simulation results are good agreement with the theory analysis.Furthermore,the simulation results of wavelength shift in terms of time are also made out for the contest of dynamic axial strain. |
