1. Diffractive Optics Design
Abstract : Diffractive optical elements (kinoforms) change the way light propagates, and can perform very complex tasks. They can split an incident beam into any number of outgoing, and possibly focused, beams (fan-out). READ MORE

2. Axicon imaging by scalar diffraction theory
Abstract : Axicons are optical elements that produce Bessel beams,i.e., long and narrow focal lines along the optical axis. Thenarrow focus makes them useful ine. READ MORE

3. Advanced Laser-based Multi-scalar Imaging for Flame Structure Visualization towards a Deepened Understanding of Premixed Turbulent Combustion
Abstract : The work presented in the thesis concerns the developments of laser-based diagnostics and its application to the study of turbulent premixed combustion. The diagnostic developments, mainly concerned with planar laser-induced fluorescence (PLIF), are intended to provide instantaneous visualization of the key species originating from the combustion processes involved in the burning of hydrocarbons and nitrogen-containing fuels under turbulent conditions.

4. Laser Diagnostics Applied to Lean Premixed Swirling Flames - Simultaneous Flow Field and Scalar Measurements
Abstract : The work reported here includes experimental studies of lean premixed swirling flames. Various laser-based optical diagnostic techniques were used to collect information under different operational conditions. Combined flow- and scalar field measurements were performed at high repetition rates for detailed studies of the turbulent flames. READ MORE

5. Detailed Soot Modelling in Laminar and Turbulent Reacting Flows
Abstract : In the present work a detailed kinetic soot model is applied to study the formation and oxidation of soot particles in laminar premixed and turbulent non-premixed flames. The soot model used in this study is based on a detailed description of the chemical and physical processes involved in the formation of soot. READ MORE
