Abstract.
It is demonstrated that multiple 1D Raman scattering, Rayleigh scattering, and laser-induced fluorescence (LIF) measurements can be performed simultaneously. This can be used for quasi-2D (or quasi-3D) single-shot measurements of multiple species and the temperature in turbulent reacting and non-reacting flows. The technique has the potential to yield more precise information than most competitive planar imaging approaches in combustion. For example, it can be used to overcome Raman/LIF interference problems in technical flames. This is achieved by a new optical set-up that makes use of an imaging spectrograph combined with fiber optics.
