  2. 1. Incident Light Fields

    Author : Jonas Unger; Anders Ynnerman; Reiner Lenz; Alan Chalmers; Linköpings universitet; []
    Keywords : Computer Graphics; Image Based Lighting; Photorealistic Rendering; Light Fields; High Dynamic Range Imaging; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : 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. READ MORE

  4. 2. Slow and stopped light by light-matter coherence control

    Author : Jonas Tidström; Lars Thylén; Mauritz Andersson; Jesper Mørk; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slow light; stored light; stopped light; light-matter coherence; electromagnetically induced transparency; rubidium atoms; Physics; Fysik; Photonics; Fotonik;

    Abstract : In this thesis we study light-matter coherence phenomena related to the interaction of a coherent laser field and the so-called Λ-system, a three-level quantum system (e.g., an atom). We observe electromagnetically induced transparency (EIT), slow and stored light in hot rubidium vapor. READ MORE

  5. 3. In Light of Ionic Materials : A short exploration of ionic materials for light-related applications

    Author : Brando Adranno; Anja-Verena Mudring; Annegret Stark; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ionic materials; ionic liquids; mesophases; light-emission; electrochemical applications; materialkemi; Materials Chemistry;

    Abstract : Ionic liquids (ILs) have been one of the most attractive classes of materials of the last decades. The reason behind this is their peculiar set of properties, which enable their possible application in several research fields. ILs are salts that exhibit a very low melting point, which has been arbitrarily defined to be below 100 °C. READ MORE

  6. 4. Computational Light Field Photography : Depth Estimation, Demosaicing, and Super-Resolution

    Author : Yongwei Li; Mårten Sjöström; Roger Olsson; Paolo Favaro; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Light field; computational photography; depth estimation; demosaicing; super-resolution;

    Abstract : The transition of camera technology from film-based cameras to digital cameras has been witnessed in the past twenty years, along with impressive technological advances in processing massively digitized media content. Today, a new evolution emerged -- the migration from 2D content to immersive perception. READ MORE

  7. 5. Electromagnetic Fields in Moving and Inhomogeneous Media

    Author : Paul Piwnicki; KTH; []
    Keywords : Moving Media; Light; Genaral Relativity;

    Abstract : The present thesis deals with electromagnetic effectscreated by the motion or inhomogeneity of a dielectricmedium.In the first paper the quantum R\"ontgen effect isdiscussed. Here a rotating Bose-Einstein condensate -- oranother kind of quantum fluid -- is placed in a chargedcapacitor. The medium's rotation creates a magnetic field. READ MORE
