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. Laser Sheet Imaging and Image Analysis for Combustion Research
Sammanfattning : This Thesis presents techniques that aim at exploiting the potential of image analysis and processing in order to solve problems of data reduction, interpolation, quantification, and interpretation within the field of experimental laser imaging of combustion processes. Combustion is the most important source of energy for power generation, heating, and transportation in the world today and its strong dominance is projected to continue in the foreseeable future.

3. Development and Application of Single-Ended Picosecond Laser Diagnostics
Sammanfattning : Light detection and ranging (lidar), a method for nonintrusive, single-ended, and range resolved measurements, has been developed and applied for combustion related diagnostics. Employing picosecond laser pulse durations and detectors providing temporal resolution on the order of picoseconds, lidar has been applied successfully for both quantitative temperature- and species concentration measurements, obtaining an ultimate range resolution of 0.

4. Combustion Studies of Soot and Fuel Based on Use of Laser Diagnostics
Sammanfattning : In the work described in the present thesis, laser techniques for combustion engine diagnostics were developed and applied. The main techniques were laser-induced incandescence (LII) and laser-induced fluorescence (LIF), used for both flame and engine diagnostics. LÄS MER
5. 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
