摘　　要：讨论了非均匀温变场对光纤光栅反射谱的影响,并针对不同的温变场模型进行了数值仿真。仿真结果表明,对于不同的非均匀温变场,在宽带光源照射下的反射谱是不同的。利用这些规律可做一般光纤光栅无法比拟的光纤光栅非均匀温变传感器以及对温变呈梳状反映的传感器。The influence on reflective spectrum of fiber grating with nonuniform temperature variation field is discussed. And numerical emulation is carried through with different modes of temperature variation fields. The results of emulation show that the reflective spectrum is different under irradiation of a wide band light source with different nonuniform temperature variation fields. Make the optical fiber grating nonuniform temperature variation field sensor and comb sensor by use of these results.
