Abstract

An active wavelength demodulation approach with high-resolution for fiber Bragg grating (FBG) sensor is proposed and demonstrated for multiplexed temperature measurement in this paper. A tunable fiber laser controlled by computer is used as the scanning light source. And the computer synchronously performs data gathering and processing. Here Gaussian-Newton curve fitting approach is used to determine the Bragg wavelength of the grating sensors. A resolution ∼±0.1pm, corresponding to ∼±0.01°C has been demonstrated using this approach.
