The Use of Non-Standard Video Techniques for Qualitative and Quantitative Flow Visualization

Abstract

A video stroboscope comprising a user-friendly sequencer to generate the trigger pulses, a frequency-independent digital phase shifter and an asynchronously shuttered progressive scan CCD camera has been developed. The basic features of this system will be explained. Examples of the application of the video stroboscope for visualization of a water jet, the inspection of the human larynx and the deformation of the model of an airplane wing will be give
