Abstract :
This paper presents a high performance distributed feedback fiber laser sensor array system. The system adopts PGC-based interferometric wavelength shift demodulation technique and wavelength division multiplexing technique. A strain resolution of 305 fε/√Hz (@ 1 kHz) and the multiplexing of eight channels have been achieved.
