  1. 1. Laser Doppler Flowmetry and Imaging: Methodological Studies

    Detta är en avhandling från Department of Clinical Physiology, Lund University

    Författare :Siv Bornmyr; [1998]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; digital photography.; cold intolerance; sympathetic nervous system; flow cessation external pressure; skin temperature; thermography; skin blood flow; laser doppler imaging; Laser doppler flowmetry; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Sammanfattning : Laser Doppler flowmetry (LDF) and laser Doppler imaging (LDI) are modern methods for non-invasive and continuous assessment of skin blood flow. The techniques are based on the phenomenon that monochromatic light transilluminating a perfused tissue is spectrally broadened owing to scattering by moving blood cells. LÄS MER

  2. 2. Laser Doppler perfusion imaging : methodology and skin applications

    Detta är en avhandling från Linköping : LJ Foto & Montage

    Författare :Karin Wårdell; [1994]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN;

    Sammanfattning : Over the last decade a number of emerging technologies have become available for the non-invasive study of skin anatomy and physiology. In this thesis, a method for mapping tissue perfusion based on the laser Doppler technique is presented together with some of the associated experimental and clinical applications. LÄS MER

  4. 4. Quantitative Laser Doppler Flowmetry

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Ingemar Fredriksson; Tomas Strömberg; Marcus Larsson; Weindelt Stenbergen; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Other technology Medical engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Medicinsk teknik;

    Sammanfattning : Laser Doppler flowmetry (LDF) is virtually the only non-invasive technique, except for other laser speckle based techniques, that enables estimation of the microcirculatory blood flow. The technique was introduced into the field of biomedical engineering in the 1970s, and a rapid evolvement followed during the 1980s with fiber based systems and improved signal analysis. LÄS MER

  5. 5. Development and application of laser diagnostics - from laboratory devices towards practical combustion engines

    Detta är en avhandling från Division of Combustion Physics, Department of Physics, Lund University

    Författare :Zhenkan Wang; [2018-05-04]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion diagnostics; Laser induced fluorescence LIF ; Ultra-high-speed; Burst-mode laser; Ballistic imaging; Particle imaging velocimetry; Laser Doppler anemometry; Turbulent premixed combustion; Plasma; Internal combustion engine; Partially premixed combustion PPC ; Auto-ignition; OH radical; CH2O formaldehyde ; Fysicumarkivet A:2018:Wang;

    Sammanfattning : For many decades, research work on combustion has been focused on improving combustion efficiency and reducing harmful emissions. Laser diagnostics is one of the best ways to investigate the combustion process and emission formation as it is non-intrusive and it has high spatiotemporal resolution. LÄS MER
