A Novel Demodulation Scheme for Fiber Bragg Grating Sensor System
IEEE PHOTONICS TECHNOLOGY LETTERS, VOL. 17, NO.1, JANUARY 2005,-0001,():
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 n and 1.59, respectively, which match the theoretical value of 1.61 very well.
