We demonstrate a new variation of molecular-tagging velocimetry for hypersonic e ows based on laser-induced e uorescence. A thin line of nitric-oxide molecules is excited with a laser beam and then, after a time delay, a e uorescence image of the displaced line is acquired. One component of velocity is determined from the time of e ight.Thismethodisappliedtomeasurethevelocityproe leinaMach8.5laminar,hypersonicboundarylayerinthe Australian National University’ s T2 free-piston shock tunnel.
