Abstract

We propose a laser sensor system which uses fiber Bragg gratings as laser cavity mirrors as well as sensors. With a spectrometer demodulation, a low-cost, more robust, and faster sensor functions have been demonstrated compared with the conventional wavelength-swept laser demodulation. Some of the multiple FBG sensors showed unstable lasing characteristics, leading to missing measurands. Polarization scrambling has been used to alleviate the problem. With fast polarization disturbances in the fiber-optic laser cavity, more FBG sensor outputs could be generated consistently and data acquisition rate has increased more than 5 times.
