| 摘 要： | 基于耦合模理论，采用传输矩阵法分析了取样光栅反射谱，取样光纤光栅在受到外界环境应变和温度影响时，其反射光谱的反射率和波长会发生变化。通过测量反射光谱的反射率变化和波长漂移，就能够实现用单根的取样光纤光栅同时测量应变和温度。通过仿真实验获得了取样光纤光栅的应变和温度传感数据。利用SPSS13.0统计学软件计算出了取样光栅反射率和波长与温度、应变变化的函数关系式，得到系数矩阵中A,B,C,D分别为-0.00033/ε,-0.00011/℃,-0.00055nm/ε,0.013nm/℃。应变测量范围为0~180

| Abstract: | Based on coupling-mode theory,the reflective spectrum of sampled fiber Bragg grating was analyzed using transmission matrix method.Wavelength shift and reflectivity vary linearly with strain and temperature.The change of strain and temperature can be determined simultaneously by a single sampled fiber grating.In the experiment,the strain and temperature of sampled fiber Bragg grating change simultaneously.The function of reflectivity and wavelength on temperature and strain can be got using SPSS13.0.We can ... |
