| 摘 要： | 提出并实验了一种有温度补偿的用于测量应力的光纤光栅传感系统。该系统用一组光纤光栅作为温度传感元件 ,对另一组应力传感的光纤光栅作温度补偿 ,有效地消除了由于温度变化而带来的应力测量误差。用一个应变仪作为系统的读出设备 ,使系统的测量结果的线性拟合度达 0 999。

| Abstract: | An in fiber Bragg gratings strain sensing system which is temperature compensated was presented and is experimented The system used a serial of in fiber Bragg gratings as temperature sensing elements and acted as temperature compensated elements to another set of in fiber Bragg gratings which are used as strain sensing elements The error induced by the shift of temperature is erased thoroughly A resistive strain gauge is employed to read out the output of the system The related linear regressive coefficient is 0 999 |
