| Abstract: |
| The tuneable fiber Fabry-Perot filter is used as demodulation device to set up fiber grating temperature demodulation system, and data signal processor(DSP) is used to carry out the exact orientation of peak value of reflective spectrum by external interrupt. The results of FBG temperature demodulation experiment show that the measuring precision of demodulation system is improved. |
