Abstract: A fiber laser-based wavelength division multiplexed sensor system with five fiber bragg grating sensor array as reflector of a ring-cavity fiber laser has been demonstrated experimently. A tunable F-P filter inside the cavity was used to interrogate the sensors and establish the laser formation. Wavelength-shift signal induced by the measured strain was demodulated by an unbalanced Michelson scanning interferometer. The sensitivity of the system was demonstrated to be 1.669°/με which was in agreement with the theoretical value of 1.678°/με well. The system was also designed to track one of the channels automatically with a feedback subsystem.
