Zusammenfassung:Tunable Diode Laser Absorption Spectroscopy (TDLAS) can offer significant opportunities and advantages for in-situ measurements of multiple parameters in gas dynamic and combustion flows. In this paper, with regard to Rocket Based Combined Cycle (RBCC), which is hydrocarbon combustion environments over the temperature range 1000-2500K, three beams diode laser sensor based on Direct Absorption Spectroscopy (DAS) for measurements of temperature, species concentration and velocity is designed by using the transitions selection criterions with different two-line schemes of water vapor in 1.25-1.65μm.
