Abstract

This paper summarizes the recent progress of improving optical fiber sensor interrogation technique by introducing acitve fiber loop into demodulation system. Various types of sensors including multimode interferometer chemical vapor sensor and etc are implemented in the active fiber loop interrogation system. The experiments show an improved signal to noise ratio by active fiber loop.
