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 laserinduced 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 rodstabilized, premixed methane-air flame, using the Q(1) (22) line of the nitric oxide A(2) Sigma(+) (v = 0) ? X(2)II((1/2))(v = 0) transition (lambda approximately 225.6 nm).
描述了一种用于测量燃烧流中二维温度场的单脉冲激光诱导荧光诊断方法。该方法利用可调谐激光的片光照明，激发稳定示踪分子中的平面激光诱导荧光，示踪分子以恒定摩尔分数注入流场。该技术的时间分辨率由激光脉冲长度决定。给出了使用一氧化氮A(2)Σ+(v = 0)→X(2)Ⅱ((1/2))(v = 0)跃迁的Q(1) (22)线（波长约为225.6 nm）对棒状稳定预混甲烷 - 空气火焰的实验结果。
