提出了一种新的单脉冲双线激光诱导氧荧光测温技术。在B（3）~（-）（u）-X（3）~（-）（g）Schumann-Runge体系的0-6和2-7带同时激发后，用多通道检测获得的荧光光谱测定了气体温度。参考相应的热电偶测量，100脉冲平均LIF温度测量的均方根误差为1.3%，在大气中的温度范围为1300-1800 K。光子散粒噪声被认为是这些测量在静态环境中的不确定性的主要来源。单脉冲温度测量不确定度（1 σ）范围从1300 K时的约13%到1800 K时的7%。
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.
