A new single-pulse, two-line laser-induced O(2) fluorescence (LIF) temperature-measurement technique was demonstrated. The fluorescence spectrum obtained with multichannel detection following simultaneous excitation of two coincident transitions in the 0-6 and the 2-7 bands of the B(3)Σ(-)(u)-X(3)Σ(-)(g) Schumann-Runge system was used to determine the gas temperature. The rms error of 100-pulse average LIF temperature measurements, referenced to their corresponding thermocouple measurements, was 1.3% over a temperature range of 1300-1800 K in atmospheric air. Photon shot noise was found to be the primary source of uncertainty for these measurements in a quiescent environment. Single-pulse temperature-measurement uncertainties (1 σ) ranged from approximately 13% at 1300 K to 7% at 1800 K.
展示了一种新的单脉冲、双线激光诱导O(2)荧光（LIF）温度测量技术。在B(3)Σ(-)(u)-X(3)Σ(-)(g)舒曼-伦格系统的0-6和2-7带中，同时激发两个重合跃迁后，通过多通道检测获得荧光光谱，用于确定气体温度。在大气环境中，100次脉冲平均LIF温度测量相对于相应热电偶测量的均方根误差在1300-1800 K温度范围内为1.3%。在静态环境中，发现光子散粒噪声是这些测量不确定度的主要来源。单脉冲温度测量不确定度（1σ）在1300 K时约为13%，在1800 K时约为7%。
