Abstract
A novel optical fiber gases sensing network system for monitoring the multi-point gas sensors is described.Using the frequency modulated continuous wave (FMCW) technique,a two-sensor array is realized for the detection of acetylene gas.Under atmospheric prseeure,the minimum detectable concentration is about 300ppm with 2.5cm gas cells.
