| Abstract: | The main principle, developing history and present status of multi-parameter and multi-functional fiber grating sensing techniques are introduced. And the technology of multi-parameters measurement at the same time with one fiber-grating sensor is explained. The discrimination techniques for cross-sensitivity of temperature and strain have been discussed in detail. The multi-parameter sensing head configurations involving fiber-grating devices have been overviewed and sorted. Novel multi-functional fiber grating sensing systems have been proposed and analyzed. |
