| 摘 要： | 报道了一种用一根光纤光栅实现温度与应变同时测量的新方案。用于同时传感温度与应变的光纤光栅写于两种不同光纤的连接处，本身具有两个反射峰。将其中半个光栅粘于热膨胀系数较大的基底材料上，这样，两个反射峰便具有不同的温度及应变响应，由此实现温度与应变的同时测量。 |

| Abstract: | A new approach for simultaneous measurement of strain and temperature using a single fiber Bragg grating is proposed and demonstrated. The fiber Bragg grating used for simultaneous measurement of strain and temperature was written on the joint of two different fibers, and has two reflection peaks at different wavelength. One section of the grating was bonded onto the substrate with large thermal expansion coefficient, so, the two reflection peaks show different strain and temperature response, and strain and temperature can be measured simultaneously. |
| Keywords: | fiber Bragg grating sensing strain |
