  4. 2. Whiteness and Fluorescence in Layered Paper and Board : Perception and Optical Modelling

    Author : Ludovic Gustafsson Coppel; Per Edström; Caisa Johansson; Markku Hauta-Kasari; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Whiteness; Perception; Colour Appearance Modelling; Paper Optics; Light Scattering; Fluorescence; Lateral Light Scattering; White-Top Mottle; Kubelka-Munk; Radiative Transfer;

    Abstract : This thesis is about modelling and predicting the perceived whiteness of plain paper from the paper composition, including fluorescent whitening agents. This involves psychophysical modelling of perceived whiteness from measurable light reflectance properties, and physical modelling of light scattering and fluorescence from the paper composition.
