A single-pulse, laser-induced-fluorescence diagnostic for the measurement of two-dimensional temperature fields in combustion flows is described. The method uses sheet illumination from a tunable laser to excite planar laser-induced fluorescence in a stable tracer molecule, seeded at constant mole fraction into the flow field. The temporal resolution of this technique is determined by the laser pulse length. Experimental results are presented for a rod-stabilized, premixed methane-air flame, using the Q/sub 1/(22) line of the nitric oxide A/sub 2/..sigma../sup +/(v = 0)reverse arrowX/sup 2/Pi/sub 1//sub ///sub 2/(v = 0) transition (lambdaapprox. =225.6 nm).
