【摘要】：探讨光纤光栅传感器(FBG)于光谱分析仪上所读取的光波频谱图的中心波长,在温度与应变作用下,测试出中心波长的漂移量与温度及应变的关系式,结果显示其温度与应变的误差可达到0.13℃及6με,并对于混凝土试件温度的重复性与稳定性都有不错的效果;对于混凝土试件的应变的量测,结果显示,FBG传感器在中心波长1 548、1 554 nm的应变与荷载关系式分别为0.256、0.235με/N。此简单、成本不高的FBG传感器若能再进一步改善后,希望能实际应用于路面结构或交通基础建设中温度与应变的量测。
[Abstract]:In this paper, the central wavelength of the optical wave spectrum which is read by the fiber grating sensor (FBG) on the spectrum analyzer is discussed. Under the action of temperature and strain, the relationship between the drift of the center wavelength and the temperature and strain is obtained. The results show that the error between temperature and strain can reach 0.13 鈩，
