Abstract
We apply light scattering to the production of species-, space-, and time-resolved images from a Sandia transparent engine, which operates with propane and air. By appropriate tuning of our KrF laser, and by treating the scattered light with an appropriate filter, we can image (a) the total density (and thus the temperature), via Rayleigh scattering, and (b) densities of OH, and of hot O2 (i.e., vibrational states 6 and 7) via laser-induced fluorescence.
