WAVELENGTH-AGILE ABSORPTION SPECTROSCOPY FOR MEASURING TEMPERATURE AND H2O MOLE FRACTION IN HARSH ENVIRONMENTS
(2009-06-24)This project develops the necessary tools and methods to measure H2O absorption spectra in harsh environments, and calculate temperature and mole fraction from the measured spectra. Various wavelength-agile sources are ... -
Wavelength-Agile Rayleigh Scattering by use of an Atomic Vapor Cell
(2005)A wavelength-agile technique using an atomic vapor cell is developed and applied to the measurement of Rayleigh scattering. The atomic vapor cell displays a steep change in refractive index as a function of wavelength, ... -
WAVELENGTH-MULTIPLEXED ABSORPTION SPECTROSCOPY APPLIED TO AN HCCI ENGINE
(2009-06-24)A new optical technique to measure real time in-cylinder temperature was developed using fiber Bragg gratings. For this aim, a time multiplexing and a frequency multiplexing sensor system were designed and developed. ...
