| Abstract: | Programmable-controlled tunable FBG-based ring fiber laser is used as the scanning light source,it is used the scheme of demodulation employing wavelength maximum scanning to detect changes of strain and temperature of FBG on this paper.The range of strain measurement is ±2440με.The sensitivity of strain measurement is 0.016step/με and the strain resolution is 61με due to the tuning sensitivity of the laser,The range of temperature measurement is 608℃.The sensitivity of temperature measurement is 0.13step/℃ and the temperature resolution is 7.6℃. |
