A summary is given of research directed toward the study of turbulent reacting and nonreacting flows by nonintrusive in situ optical techniques. During the funding period, new diagnostic techniques were developed for the instantaneous mapping of species concentration and temperature in turbulent flames in one or two dimensions. A number of different light scattering mechanisms were utilized including Rayleigh scattering, spontaneous Raman scattering, and coherent anti-Stokes Raman scattering (CARS). Progress was also made on the use of newly-available, high-speed imaging devices which allow the two-dimensional mapping of the flows at rates high enough to follow their temporal evolution. 9 refs., 4 figs.
