Abstract
A remote multiplexed methane sensor system taking advantage of low cost 1.33 1&mgr;m SLD is demonstrated. it has long time stabilization, immunize from the influence of the temperature changing. Reference light is adopted in the system to reduce the affection of attenuation caused by long distance transmission of light in fiber and the drift of the SLD output power. Resolution of 0.01% (10-s time constant) is obtained by introducing intensity modulation and Lock-In-Amp.
