摘要:An accurate de-multiplexing mathematical model is established for
optical fiber Fabry-Perot (F-P) cavity and Fiber Bragg Grating (FBG)
multiplexed sensor. The spectral characteristic of the sensor is
analyzed and a new mechanism to separate FBG spectrum from F-P cavity
spectrum is proposed, with a swept laser based wave length
interrogator,the experimental results demonstrate that the cross
interfer-ence between F-P sensor spectrum and FBG sensor spectrum is
clearly eliminated,and the resolution of the sensor system is
effectively improved with the new demodulation mechanism. The maximum
uncer-tainty of 0. 2nm and 0. 7pm has been achieved for the F-P cavity
length and FBG peak wavelength meas-urement respectively.
