The prospects for two-dimensional imaging of conserved scalars in turbulent flames are investigated. It is shown that two simultaneous scalar measurements are required, and that there are several options, such as the Raman fuel-Rayleigh, Raman oxidant-Rayleigh and Raman fuel-Raman oxidant combinations. Measurements in turbulent and laminar flames are used to demonstrate the advantages and weaknesses of these alternatives: the Raman fuel-Rayleigh pair appears to be the most viable where dust and soot particles are absent. The Raman fuel-O2 pair has certain advantages in the presence of dust and solid scattering surfaces but is more susceptible to bias from soot precursor interference.
