摘要:
设计了一种基于取样光纤光栅的温度-应变交叉传感器,应变测量范围为0~2 000 με,温度测量范围为-50~200℃.仿真验证获取了取样光纤光栅的传感特性.应用SPSS统计学软件,得到取样光栅同时测量温度和应变的双参量矩阵方程,并标定了矩阵方程中的4个传感系数.

Abstract:
In this paper,a cross-sensitive temperature and strain sensor based on sampled fiber grating is designed.Its temperature measurement range is -50-200℃,and the strain measurement rangeis 0-2 000 με.The characteristics of the sensor are obtained using simulation method.Utilizing SPSS software,we found the dual-parameter matrix equations of measurement of temperature and strain,and calibrated the four sensing coefficients of the matrix equations.
