Kurzfassung
A high-speed video stroboscope has been developed at DLR, which allows the investigation of fast repetitive, e.g. periodic, phenomena. It provides a real-time, slow-motion display of these events with simultaneous frame recording. The system comprises a user-friendly sequencer to generate the trigger pulses, a frequency-independent digital phase shifter and an asynchronously shuttered progressive scan CCD camera. The basic features of this system and its recent extension to a multicamera system will be described. Examples of the application of the video stroboscope for the measurement of the gap width of a high lift device in-flight, for the diagnostics of a turbine and for the investigation of the cavitation effect behind a marine propeller will be given.
