摘　　要：对光纤光栅的温度和应力特性进行了实验研究，表明光纤光栅的Ｂｒａｇｇ波长随温度和轴向应变的变化呈现出良好的线性关系，这一实验结果可以作为对光纤光栅进一步深入研究的参考。The properties of temperature and stress for fiber Bragg gratings have been studied experimentally in this paper. Experimental results show that the Bragg wavelength of optical fiber grating is linear with its temperature and its axial strain. Our experimental results can provide guidance for farther studying on fiber Bragg gratings.
