Abstract
- A novel fiber Bragg grating (FBG) wavelength demodulation scheme based on a compound interference configuration is introduced. This scheme measures the strain-induced wavelength-shift of the FBG in terms of phase-shift signal. The sensing resolution and sensitivity were demonstrated to be 6.2 nε and 1.59°/με, respectively, which match the theoretical value of 1.61°/με very well. [ABSTRACT FROM PUBLISHER]
