1. Development of Dual-broadband Rotational CARS for Combustion Diagnostics
Abstract : The present thesis concerns development and application of dual-broadband rotational coherent anti-Stokes Raman spectroscopy (DB-RCARS) for temperature and species concentration measurements in combustion processes. Both fundamental development of the technique, including experimental as well as modelling results, and measurements in practical combustion devices were conducted. READ MORE

2. Modelling and Applications of the Hollow Cathode Plasma
Abstract : This thesis presents experimental and modelling research on atmospheric pressure hollow cathodes and hollow electrodes. Experiments with the hybrid hollow electrode activated discharge (H-HEAD), which is a combination of a hollow cathode and a microwave plasma source, is presented. READ MORE

3. Infrared Laser-Induced Grating Techniques for Diagnostics in Reactive Flows
Abstract : AbstractThe work presented in this thesis is mainly focused on the development andapplication of infrared laser-induced grating techniques in order to measure the gasphase temperature and species concentrations in reactive flows. The two techniquesused for this purpose are laser-induced grating spectroscopy (LIGS) and degeneratefour-wave mixing (DFWM). READ MORE

4. Laser Diagnostics in Combustion - Elastic Scattering and Picosecond Laser-Induced Fluorescence
Abstract : 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).

5. Methods, Instrumentation and Mechanisms for Optical Characterization of Tissue and Treatment of Malignant Tumours
Abstract : In this thesis, different optical methods utilising visible light for characterization of tissue have been developed and evaluated. The feasibility of many of these methods has been demonstrated in the laboratory or in animal experiments. READ MORE
