Multiline absorption spectroscopy for methane gas detection
Multiline absorption spectroscopy for methane gas detection is a scholarly work, published in 2006 in ''Applied Optics''. The main subjects of the publication include wavelength, materials science, optics, interferometry, Differential optical absorption spectroscopy, silicon photonics, methane, spectroscopy, tunable diode laser absorption spectroscopy, Analytical Chemistry, Cavity ring-down spectroscopy, absorption, and absorption spectroscopy. The authors demonstrate a minimum-detectable concentration of 7600 +/- 10% ppm (parts per million) with a multiline differential absorption spectroscopy technique and a concentration of 1000 +/- 10% ppm with a multiline wavelength modulation spectroscopy technique.
