  5. 9. Diode-laser absorption spectroscopy - applications in medicine and environmental monitoring

    Författare :Jim Larsson; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TDLAS; GASMAS; biophotonics; Scheimpflug Lidar; Fysicumarkivet A:2019:Larsson;

    Sammanfattning : A major part of this thesis work has been research in a medical project, where, together with industry and clinical partners, the aim was to develop a prototype system for non-invasive monitoring of premature babies based on the optical measurement technique gas in scattering media absorption spectroscopy (GASMAS). Part of the project was to develop a 3D-printed tissue phantom based on chest X-ray images of the thorax of a premature infant. LÄS MER

  7. 10. Two-Line Atomic Fluorescence for Thermometry in Reactive Flows

    Författare :Jesper Borggren; Förbränningsfysik; []
    Nyckelord :Two-line atomic fluorescence; thermometry; Laser spectroscopy; Diode laser; Fysicumarkivet A:2018:Borggren;

    Sammanfattning : Advances in the field of laser-based combustion diagnostics over the past decades have allowed for detailed characterisation, modelling and increased understanding of the complex combustion process. However; many combustion phenomena are still unexplained and there is a continued need for development and application of diagnostic tools to further the understanding of the combustion process.
