Spatially resolved visualization of a high-speed airflow around a model by laser-induced fluorescence

A poster paper reported the further development of a laser resonant Doppler velocimeter technique in flow field visualization around a model in supersonic air. Iodine vapour was used to seed the air flow. Tuning of expanded narrow linewidth laser beam is used to induce regions in the flow with a specific velocity component fluoresce brightly. (P.J.B.)
