Absorption measurement of methane gas with broadband light source using fiber-optic sensor system
Absorption measurement of methane gas with broadband light source using fiber-optic sensor system
摘要
Abstract
The absorption coefficient of methane is very important for measuring the concentration of methane. We theoretically analyzed the general expression of methane absorption coefficient for a given condition, at room temperature of 296 K, and we simulated the relationship between the absorption and the wavelength of the light source. The experimental results we obtained are consistent with the simulation. The discrepancy between the experimental results and the simulation results is also discussed.
