Abstract

Spontaneous Raman spectra have been recorded in a non-combusting methane/air mixture using KrF laser excitation and an imaging grating spectrograph equipped with a two-dimensional detector. If the entrance slit of the spectrograph is broadened, the resulting Raman images will contain a convolution of spatial and spectral information. The two-dimensional spatial information on the individual molecular species that contribute to the Raman image can be retrieved by a deconvolution procedure. This is demonstrated for two selected regions in the flow, for which mixing ratios are presented.
