title: Molecular velocity imaging of supersonic flows using pulsed planar laser-induced fluorescence of NO.
abstract: A technique is described for imaging components of velocity in a gaseous flow field by using pulsed planar laser-induced fluorescence. The technique is based on the fluorescence detection of Doppler-shifted absorption that results when a spectrally narrow absorption line is excited with a broadband laser. Results obtained in a Mach 7 underexpanded supersonic jet, seeded with NO, are presented. The practical extension of this technique to single-shot measurements of two velocity components is discussed.
