摘要：
A method using fiber Fabry-Perot tunable filter to achieve FBG sensor's Bragg wavelength is described. The system has the capability to interrogate large number of DFB sensors, whilst obtaining absolute Bragg wavelength with pm resolution. A demonstration system with 4 strain sensors is presented, which obtains DFB sensor's absolute strain value and achieves sub-microstrain resolution at 300Hz interrogating rate.
