  1. 1. Incident Light Fields

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Jonas Unger; Linköpings universitet.; Linköpings universitet.; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Graphics; Image Based Lighting; Photorealistic Rendering; Light Fields; High Dynamic Range Imaging; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Image based lighting, (IBL), is a computer graphics technique for creating photorealistic renderings of synthetic objects such that they can be placed into real world scenes. IBL has been widely recognized and is today used in commercial production pipelines. However, the current techniques only use illumination captured at a single point in space. LÄS MER

  2. 2. Intraocular light scattering and glare testing

    Detta är en avhandling från Göteborg

    Författare :Jörgen Thaung; Göteborgs universitet.; Gothenburg University.; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; light scattering; light scattering factor; glare; veling luminance; contrast sensitivity; adaptation; psychophysics; light transmission; integrating sphere; human lens; cataract; aging.;

    Sammanfattning : Aims: To analyze the parameters that are used in psychophysical glare testing and the validity of the light scattering factor (LSF). The purpose is also to investigate the light scattering properties in excised eye lenses, and to compare these properties with light transmission for different wavelengths in aging and cataractous lenses.

  4. 4. Celestial Orientation in Dim Light

    Detta är en avhandling från Marie Dacke, Deparment of Cell and Organism Biology, Lund University

    Författare :Marie Dacke; Lund University.; Lunds universitet.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polarisation pattern; moon; polrised light detection; twilight; dim light; dung beetle; Zoologi; spider; vision; orientation; Zoology;

    Sammanfattning : The polarization pattern of skylight offers many animals a reference for visual compass orientation. In those cases when this optical compass is identified, the receptors involved are often confined to a small part of an eye built predominantly for other visual tasks. LÄS MER

  5. 5. Polymer light-emitting electrochemical cells Utilizing doping for generation of light

    Detta är en avhandling från Umeå : Department of Physics, Umeå University

    Författare :Piotr Matyba; Umeå universitet.; [2011]
    Nyckelord :;

    Sammanfattning :     The current implementation of conjugated polymers (“conducting plastics”) in a wide range of devices promises to bring the vision of a new generation of flexible, efficient and low-cost applications to reality. Plastic lightemitting devices in the form of polymer light-emitting diodes (PLEDs) are projected to be particularly close to the market in applications such as large area and conformable illumination panels and high-performance thin displays.
