A temperature demodulation method by using compensation of fiber attenuation and dispersion for distributed temperature sensors (DTS) is proposed and demonstrated in order to improve the DTS measuring speed and accuracy. Firstly, the attenuation coefficients difference between anti-Stokes and Stokes backscattering is modified, which avoids the calibration processing on the entire sensing optical fiber...
The temperature properties of bismuth active centers (BACs) on Bismuth/Erbium co-Doped Optical Fibers (BEDFs) have been demonstrated and the reasons of this phenomenon are explained. The possibility of temperature sensor based BEDFs has also been discussed.
We investigate the photosensitivity and demonstrate strong grating writing and distributed feedback (DFB) fibre laser fabrication in Bi/Er co-doped germanosilicate optical fibre (BEDF) with broadband emission.
We proposed a novel intensity modulation based composite cavity optical fiber laser (CCFL) sensor, which is suitable for the vibration measurement. The intensity modulation of the CCFL is caused by the modulation of the weak feedback of the CCFL. The weak feedback of the CCFL is based on the end face reflection and the Rayleigh scattering of optical fiber. An acoustic measurement of the CCFL sensor...
