摘要：

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) Sigma(u)(-)-X(3) Sigma(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 sigma) ranged from approximately 13% at 1300 K to 7% at 1800 K.
