1. Blue Laser Source for Laser-Induced Fluorescence
Sammanfattning : Laser-induced fluorescence is a clinical diagnostic tool, used for tumor demarcation and detection. The technique relies on the injection or topical application of a light sensitive drug called a photosensitizer. This substance has the ability to be accumulated to higher concentrations in cancer cells than in normal cells. LÄS MER
2. Development and Application of Laser-Induced Emission Techniques for Combustion Diagnostics -High-Resolution Visualization of Turbulent Reacting Flows
Sammanfattning : Nowadays, more than 90% of our energy comes from combustion processes. Hence, it is very important to perform combustion research to reduce emissions, improve efficiency, find clean and renewable fuels, strengthen safety, etc. LÄS MER
3. 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
4. Development of Laser-Induced Fluorescence for Precombustion Diagnostics in Spark-Ignition Engines
Sammanfattning : Motivated by a desire to understand and optimize combustion in spark-ignition (SI) engines, laser techniques have been developed for measurement of fuel and residual gas, respectively, in the precombustion mixture of an operating SI engine. The primary objective was to obtain two-dimensional, quantitative data in the vicinity of the spark gap at the time of ignition. LÄS MER
5. Laser-Induced Emission Techniques for Concentration and Temperature Probing in Combustion
Sammanfattning : The work in this thesis is aimed at the development of temperature and gas concentration measurement techniques in laser diagnostics for use in combustion research. The techniques are developed as tools for the combustion community to meet future demands on combustion efficiency and legislation of exhaust gases. LÄS MER
