| Abstract: |
| This article aims to review several typical fiber grating sensors and their applications in the field of sensing. First, the basic principles of fiber grating sensing are introduced, and then the structure and optical characteristics of Bragg gratings, long-period gratings, tilted gratings and chirped gratings are explained. Finally, the application of fiber grating sensors in temperature sensing, structural health monitoring, corrosion research, the shortcomings in application and future development directionsare described. |
