Abstract
We propose a region selectable gas sensing system, which can address gases of single and/or different species at multilocations. This technique is based on optical spectroscopy of each selected numerous absorption lines of gas. Primary experiment using fiber-optic absorption sensors, sensing regions and region selectors are demonstrated. Specific FBGs are employed to reflect the selected spectrum for each sensing region. FBG monitor what encloses the tunable light source and spectrum analyzer works as selected gas and region absorptions measurement. Absorption ratio was estimated which indicates that the technique is applicable in lightweight fiber optic wide-regions gas sensing.
