【摘要】 根据Kogelnik给出的光栅反射系数方程，本文仔细分析了呈均匀分布、线性分布、三角形分布、高斯分布、正锥形分布等情况的应变对光纤光栅反射谱影响。一方面给光纤光栅传感器提供帮助，另一方面也可以为光纤光栅的特性研究提供有益的参考。更多还原

【Abstract】 According to Kogelnik’ s equation of grating reflection coefficient, we analysis the effect of the different strain profile, including uniformity, linearity, triangle,Gauss and positive taper etc., on fiber Bragg grating (FBG). it is helpful to both the research of the FBG sensor and the study of the characteristics of FBG.更多还原
