A brief account is given of progress in developing new nonintrusive in situ optical techniques and applying these techniques to study turbulent reacting flows. Progress has been made in three main areas: (1) the use of Rayleigh scattering to map the instantaneous spatial concentration field at 10,000 points within a nonreacting turbulent flow; (2) the initiation of Ramanography experiments for measuring the instantaneous concentration field of various gas components within a turbulent diffusion flame; and (3) the feasibility of using CARS for making spatially resolved flame temperature measurements within a turbulent diffusion flame.
