1. 1. Application of Diode Laser Molecular Absorption Spectroscopy for Studies of Gas Concentrations in Food Packages

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

   Author : Jan Von Keitz; [2014]
   Keywords : Diode Laser Spectroscopy Gas Concentration Food Packages; Physics and Astronomy;

   Abstract : When it comes to absorbing and emitting radiation, molecules show similar properties as atoms do. A signicant dierence though, is that a molecular spectrum consists of notably more absorption lines compared to an atomic spectrum. READ MORE

3. 2. Laser spectroscopic studies on scattering media - Application to food packages and wood materials

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

   Author : Jim Larsson; [2014]
   Keywords : food packages; absorption spectroscopy; wood; diode lasers; scattering media; Physics and Astronomy;

   Abstract : In this project, an optical technique called gas in scattering media absorption spectroscopy (GASMAS) has been employed to investigate optical properties in scattering media such as food packages and wood materials. The GASMAS technique has been combined with a technique called frequency domain photon migration (FDPM) and from the integrated system the gas absorption signal and total optical path length have been assessed when measuring on milk packages.
