The present study, which has demonstrated the feasibility of using time-resolved laser-induced fluorescence methods to ascertain boundary layer temperature distributions in real time for hypersonic vehicles in atmospheric flight, employs conventional optics in combination with novel time-resolved spectroscopy. The radiative lifetime and signal intensity involved, both of which are reduced by quenching, are adequate for measurement with state-of-the-art time-resolved fluorescence techniques, except for certain conditions associated with both the highest speeds and the lowest altitudes.
