Particle Image Velocimetry (PIV) is increasingly used to investigate unsteady velocity fields instanteneously. For the first time, the PIV technique allows the recording of a complete velocity field in a plane of the flow within microseconds. This does not only give information about unsteady flow fields otherwise not obtainable but also helps to save operational time in the wind tunnel. At DLR a set up for PIV has been developed which can be operated under the rough environmental condition (noise, vibrations) of a large wind tunnel. This system has been successfullyapplied to lwo-speed as well as to high-speed flow (U = 10. 500 m/s). The evaluation and post processing of the PIV recordings run fully automatically on a workstation.
