Paper Abstract

We demonstrate a passive fiber Bragg grating sensor demodulator based on the wavelength-dependent transmission of long period grating filters. Strain resolution of the system was 1 (mu) (epsilon) for dc strain in a 3.3 Hz bandwidth. Quasi-static and dynamic operation of the system were investigated.
