| Abstract: | The paper reviews the sensing principle, fabrication techniques of fiber Bragg gratings (FBG) and their applications in sensors. Two solutions to temperature and strain cross_sensitivity, which are intrinsic problems of FBG,are described in detail. With these solutions, more accurate information about strain and temperature can be obtained simultaneously. The FBG's application_3s system and the problems met in the project are mentioned. It is demonstrated that the FBE used in sensing technology is superior to other technologies. |
