1. Laser Scanning Multiphoton Microscopy – Focusing on Fluorescence Correlation Spectroscopy and Fluorescence Lifetime Imaging for Biomedical Applications
Sammanfattning : Laser scanning multiphoton microscopy (MPM) is considered as a non-invasive technology for three-dimensional imaging of complex biological tissues. The quantitative potential of the MPM is not investigated as much as qualitative imaging. LÄS MER
2. Short-Pulse Laser Spectroscopy for Combustion Diagnostics - Laser-Induced Fluorescence of Polyatomic Molecules and Developments in Measurement and Evaluation
Sammanfattning : Combustion is the most important source of energy worldwide. A better understanding of it is essential if pollutant emissions are to be reduced and combustion devices be made more efficient. This requires measurement of physical and chemical combustion parameters. LÄS MER
3. Multiphoton Microscopy Targeting Tissue Development. Towards the real-time imaging of epidermal differentiation
Sammanfattning : The development of novel organ-on-a-chip models calls for methodologies, which will allow the study of tissue development and pharmacological outcome in real-time. Multiphoton microscopy (MPM) has been proposed as a suitable technique for noninvasive imaging of live specimens, utilizing intrinsic tissue fluorescence. LÄS MER
4. Development and application of photofragmentation laser-induced fluorescence for visualization of hydrogen peroxides
Sammanfattning : The work presented in this thesis is mainly motivated by the need for an optical diagnostic technique which can be used to visualize hydrogen peroxide (H2O2) in its gas phase. Due to the lack of bound electronic states, H2O2 cannot be detected using laser-induced fluorescence based on electronic excitation. LÄS MER
5. Laser Diagnostics in Combustion - Elastic Scattering and Picosecond Laser-Induced Fluorescence
Sammanfattning : Elastic scattering and the Lorenz-Mie (LM) theory in particular is used for the characterization of sub-micron- and micron-sized droplets of organic fuels in sprays and aerosols. Calculations on the Lorenz- Mie theory show that backward-sideward scattered visible radiation can be used for unambiguous detection of ensembles of homogeneous droplets of organic substances with diameters around 1 micrometer (size parameter between 2 and 6).
