| 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传感方案。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。由于两种光纤的光热系数不同 ,两个反射峰具有不同的温度响应。通过监测两个反射峰的波长移动便可实现温度与应变的同时测量。 |

| Abstract: | A new approach for simultaneous strain and temperature measurement using a single fiber Bragg grating has been reported in this paper. The fiber Bragg grating used for simultaneous strain and temperature measurement is written on the joint of two different fibers, and has two reflection-peaks at different wavelength, which have different temperature response because of the different thermo-optic coefficients for the two fibers. By measuring wavelength shift of the two peaks, strain and temperature can be determined simultaneously. |
| Keywords: | fiber Bragg grating sensing temperature strain |
