  4. 2. Light Propagation and Gas Absorption Studies in Turbid Media Using Tunable Diode Llaser Techniques

    Author : Liang Mei; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gas in scattering media absorption spectroscopy; tunable diode laser absorption spectroscopy; frequency modulated light scattering interferometry; light propagation; Absorption spectroscopy; turbid media; diode laser; gas monitoring; porous media; ceramics; food packaging; Fysicumarkivet A:2014:Mei;

    Abstract : Optical absorption spectroscopy is a widely used analytical tool for constituent analysis in many applications. According to the Beer-Lambert law, the transmitted light intensity through a homogeneous medium is an exponential function of the product of the concentration, the total pathlength, and the absorption cross-section of the absorbing substance.
