Laser-based combustion diagnostics which yield multi-dimensional data sets (e.g., 2-D, 3-D or 2-D plus time) are currently under .investigation in several laboratories. Work thus far has emphasized Planar Laser-Induced Fluorescence (PLIF), owing particularly to its signal strength and species sensitivity, but alternative sensing strategies based on Rayleigh, Raman and degenerative four-wave mixing (DFWM) concepts are also of interest. In all cases, significant progress is being made owing to advances in laser systems, solid-state camera technology and improved understanding of laser-gas interactions, especially at high spectral intensities. |
