Abstract

We review the spontaneous Raman scattering process as applied to the determination of species concentration and thermometry in turbulent reactive flows. Comments on design improvements to the apparatus are made. We elaborate on a matrix formulation for data reduction that logically removes the following undesired sources of signal in Raman scattering systems: 1) cross-talk due to Raman scattering from other species, 2) laser induced fluorescence, 3) background flame chemiluminescence, and 4) noise in the data acquisition system.
