Abstract
Two-dimensional temperature measurements using filtered Rayleigh scattering (FRS) have been demonstrated. A tunable single-longitudinalmode alexandrite laser was employed to provide the tunable narrow-linewidth ultraviolet laser beam at 254 nm. Isotopic-enhanced mercury was utilized as an ultraviolet atomic filter. The strong absorption of the filter enabled effective suppression of elastic background. The transmission curve of the mercury filter was characterized by combining experimental measurements and proper modeling. The Rayleigh-Brillouin spectral profiles were calculated employing the S6 model. Quantitative interpre_ tations of two-dimensional FRS signals were performed in both premixed and diffusion flames. The temperature values... (More)
