    Author : Niklas Johansson; Per Edström; Mattias Andersson; Magnus Neuman; Jon Yngve Hardeberg; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; goniophotometry; anisotropy; angle resolved light scattering; reflectance measurements; turbid media;

    Abstract : Avhandlingen behandlar de teoretiska och praktiska aspekterna av att använda spektrala vinkelupplösta reflektansmätningar för optisk karakterisering av fiberbaserade material såsom papper och kartong. En spektral goniofotometer används för att mäta det reflekterade ljusets vinkelfördelning. READ MORE

  4. 2. Development of wavelength modulation diode laser absorption spectrometry in transversely heated graphite atomisers for sensitive trace element analysis

    Author : Jörgen Gustafsson; Umeå universitet; []
