One of the key issues in establishing an optical fiber sensing system based on fiber Bragg gratings (FBGs) is the selection of a suitable wavelength shift detection scheme in terms of the performance it offers. By use of a compact Fabry-Perot (F-P) tunable filter, the Bragg wavelength variation can be detected with a relatively high speed and satisfying resolution
