This Phase II STTR project will continue the research and development of a simultaneous multi-species sensor system for scramjets flight test instrumentation. The sensor system is based on modulation-frequency multiplexing to combine several laser wavelengths and using a single two-color photodiode detector to collect the laser signals along the same optical path. High-sensitivity detection of chemical species concentrations can be achieved using wavelength modulation spectroscopy. Fiberization of the laser sources and utilization of custom electronics will enable a rugged, compact, stand-alone multi-species sensor system to be developed. A prototype instrument will be built, calibrated in a heated calibration cell and premixed flat flame burner, and tested in supersonic combustion tunnels. The sensor will be capable of measuring methane, water vapor and oxygen concentrations, and temperature simultaneously.
