Combustion processes, if uncontrolled, are inherently inefficient and increasing the efficiency of combustion in engines, gas burners and furnaces is a significant challenge for the future due to limited fossil fuel resources and their effects on the environment. To examine the structure and composition of flames requires cutting edge laser imaging techniques such as Laser Induced Fluorescence (LIF), Laser Particle Image Velocimetry (PIV), scattering experiments (Raman-, Rayleigh- and Mie-) and Spectroscopy (Emission and Absorption) . These techniques are favoured and commonly used as they allow non-invasive multi-parameter measurements with high resolution. Some of the most commonly used laser diagnostics techniques to examine complex combustion processes are Particle Image Velocimetry and Planar Laser-Induced Fluorescence (PLIF) and, and to a lesser extent chemiluminescence. These form the backbone of the science of combustion imaging and diagnostics and are ideal for in-situ real-time recording of the complex dynamic gas and fuel processes occurring in a flame.
