    Sammanfattning : Elastic scattering and the Lorenz-Mie (LM) theory in particular is used for the characterization of sub-micron- and micron-sized droplets of organic fuels in sprays and aerosols. Calculations on the Lorenz- Mie theory show that backward-sideward scattered visible radiation can be used for unambiguous detection of ensembles of homogeneous droplets of organic substances with diameters around 1 micrometer (size parameter between 2 and 6).

    Sammanfattning : Radiative transfer models are used to describe optical properties of polymericthick films containing spherical inhomogeneities with sizes comparable to thewavelength of the incident radiation. From Lorenz-Mie theory various parametersrelated to elastic light scattering and absorption by single particles are calculated, i.e. LÄS MER

  5. 4. Optical Scattering Properties of Pigmented Foils for Radiative Cooling and Water Condensation: Theory and Experiment

    Författare :Torbjörn M. J. Nilsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Light scattering properties of inhomogeneous materials were investigated in this thesis. Optical properties of pigmented polyethylene foils were optimized to take advantage of radiative cooling and for water condensation. LÄS MER

  7. 5. 3D localization in digital holography from scattered light from micrometer-sized particles

    Författare :Johan Öhman; Mikael Sjödahl; Per Bergström; Erik Olsson; Torbjörn Löfqvist; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital Holography; Polarization; Particle Scattering; Metrology; Experimentell mekanik; Experimental Mechanics;

    Sammanfattning : When a particle is illuminated by a beam of light it will scatter and redistribute the light in all directions. How it scatters depends on the size, shape and refractive index of the particle. Additionally, it depends on the wavelength and polarization of the illuminating beam. LÄS MER
