Paper Abstract

In this paper, we present the experimental results of a research investigation for a hollow waveguide based fiber optic sensing device for simultaneous multiple gas detection. Gas molecules that exhibit characteristic vibrational absorption lines in the near-IR region that correspond to the transmission window for silica optical fiber have been detected by this device. An experimental setup was constructed, a fiber optic sensing device was designed and demonstrated which can monitor multiple gases simultaneously. The experimental results clearly demonstrate the characteristic absorptions in the optical spectra corresponding to the narrow molecular absorption lines of the gases tested that included acetylene and carbon monoxide.
