Laser-Induced Fluorescence (LIF) is the most powerful technique for experimental diagnostics of combustion processes available today.

Based on the physics of interaction between light and molecules, Laser-Induced Fluorescence allows for species selective measurements with high sensitivity. This allows measurements of minor combustion species to be made. The technique is non-intrusive and provides in-situ information with high spatial and temporal resolution.

Combustion radicals and products by Laser-Induced Fluorescence (LIF)

Our highly advanced and flexible system for combustion LIF is capable of measuring a wide range of combustion radicals and products.

Combustion Laser-Induced Fluorescence (LIF) solutions can be combined with other measurement solutions like PIV to perform multi-parameter measurements. The video below shows data from a combined time-resolved OH-LIF and PIV system on a lifted flame in a low-swirl burner. This application uses the OH radical as a flame front tracer. The interaction between the chemistry and fluid-mechanics in combustion processes can be investigated when the OH-LIF and PIV data are combined
