| Abstract: | The basic theoretical analysis and the experimental study for the temperature dependence of characteristics,also the compensation and the sensitivity enhanced of FBG temperature are made.The experimental results show that its temperature characteristics present linearity,a kind of the temperature compensation device which is used for the testing can eliminate the influence on wavelength shifting caused by the temperature and improve the temperature sensing ability of FBG.The sensitivity coefficient is 9.3 times as much as that of bare fiber grating. |
| Keywords: | fiber Bragg grating temperature sensitivity enhanced temperature-compensating |
