Abstract

A novel scheme for a code-division multiplexing based fiber Bragg grating sensor system is theoretically analyzed and experimentally demonstrated. The results show that the proposed scheme enables an improved signal-to-noise ratio performance compared with the time-division multiplexing method and that spontaneous-spontaneous beating noise should be included in the analysis to avoid overestimation. The simple and effective setup provides a competitive approach for using fiber Bragg grating sensors in practical application systems.
