Abstract

An eight element time-division multiplexed fiber Bragg grating sensor array is demonstrated using an unbalanced integrated-optic discriminator to facilitate demodulation of Bragg wavelength shifts in the return signals. The system exhibits a wide sensing range with a detection capability of <1 (mu) - strain/(root)Hz rms at low frequencies.
