摘要

本文利用MATLAB研究了纵向应变和温度对均匀光纤布拉格光栅(FBG)的影响。在人类受限制的地方，测量各种应用中的应变或温度是必不可少的。光纤技术为基于光纤光栅的传感器测量应变或温度提供了更好的结果。模拟结果表明，当施加2000微应变时，Bragg波长偏移2.4 nm，在120℃温度下，Bragg波长偏移1.65 nm。传感器的检测灵敏度为1.2 pm/µε和13.7 pm/0C。它还强调了温度和应变对fbg的综合影响，使Bragg波长峰在波长上发生更多的位移。在120℃下，2000微应变和温度的共同作用下，Bragg波长发生了4 nm的位移。

Effect of Strain and Temperature on FBG

In this paper, the effect of longitudinal strain and temperature on uniform Fiber Bragg Grating (FBG) is investigated using MATLAB. Measurement of strain or temperature in various applications is essential where mankind is restricted. Fiber optic technology gives a better result for the measurement of strain or temperature using FBG based sensors. The simulated results show that a 2.4 nm shift in Bragg wavelength for the applied 2000 microstrain, 1.65 nm shift in Bragg wavelength at 120 0C temperature. The detection sensitivity of the sensor is 1.2 pm/µε and 13.7 pm/0C. It also emphasizes that the combined effect of temperature and strain on FBGs, shifts the Bragg wavelength peak more in wavelengths. A 4 nm shift in Bragg wavelength is also observed for the combined effect of 2000 microstrain and temperature at 120 0C.
