  2. 1. Synthesis, Coding, and Evaluation of 3D Images Based on Integral Imaging

    Author : Roger Olsson; Youzhi Xu; Mårten Sjöström; Tingting Zhang; Aljoscha Smolic; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integral Imaging; 3D images; coding; quality evaluation; H.264 AVC; JP3D; Telecommunication; Telekommunikation;

    Abstract : In recent years camera prototypes based on Integral Imaging (II) have emerged that are capable of capturing three-dimensional (3D) images. When being viewed on a 3D display, these II-pictures convey depth and content that realistically change perspective as the viewer changes the viewing position. READ MORE

  4. 2. Energy and intensity modulated radiation therapy with electrons

    Author : Lennart Olofsson; Mikael Karlsson; Magnus Karlsson; Björn Zackrisson; Erik Traneus; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; Radiation therapy; Conformal therapy; IMRT; Electrons; Electron treatment head; Electron MLC; Bremsstrahlung reduction; Integral dose; Penumbra; Output factor; Strålningsvetenskap; Radiation biology; Strålningsbiologi; radiofysik; radiation physics;

    Abstract : In recent years intensity modulated radiation therapy with photons (xIMRT) has gained attention due to its ability to reduce the dose in the tissues close to the tumour volume. However, this technique also results in a large low dose volume. READ MORE

  5. 3. High-contrast imaging of low-mass companions and debris disks

    Author : Ruben Asensio Torres; Markus Janson; Subhanjoy Mohanty; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Direct imaging; extrasolar planets; debris disks; planet formation; high angular resolution; Astronomy; astronomi;

    Abstract : The search for exoplanets, i.e., planets orbiting other stars than the Sun, is a relatively new research field, but has already established itself as one of the most prolific and intriguing areas of astronomy. READ MORE

  6. 4. Inversion of circular averages and application of backprojection methods to radar imaging

    Author : Stefan Nilsson; Linköpings universitet; []
    Keywords : inverse problem; backprojection; tomography; integral geometry;

    Abstract : In this report we study two mathematical inverse problems concerning the determination of a function from spherical averages, which appear in certain radar applications. The first inverse problem consists of determining a function from its spherical averages over all circles with center on a straight line and with arbitrary radius. READ MORE

  7. 5. Axicon imaging by scalar diffraction theory

    Author : Anna Burvall; KTH; []
    Keywords : axicons; diffractive optics; coherence; asymptotic methods; communication modes; information content; inverse problems;

    Abstract : Axicons are optical elements that produce Bessel beams,i.e., long and narrow focal lines along the optical axis. Thenarrow focus makes them useful ine. READ MORE
