Abstract
Ozone tagging velocimetry is developed for unseeded velocity measurement of air flows. An ozone line is photochemically created by an ArF excimer laser. After a fixed time delay the ozone line is imaged with a KrF excimer laser sheet (248 nm) that photodissociates the ozone and produces vibrationally excited O2. The O2 is excited by the same 248-nm light through the Schumann-Runge band, B 3Σu-(υ′ =0, 2) ← X 3Σg-(υ″ = 6, 7). An intensified CCD camera records the O2 fluorescence from the initial and the final line positions to permit the velocity profile along the line to be determined.
