Abstract

The performance of a time-division-multiplexed fiber Bragg grating sensor array that uses a tunable laser source has been investigated. It was found that the wavelength detection accuracy is affected by the extinction ratio of the optical pulse modulator used for input pulse generation. Experiments with a 4-FBG sensor array demonstrated a strain resolution of 0.7 με with an optical pulse modulator of -24-dB extinction ratio. Microwave Opt. Technol. Lett.
