Many investigators of experimental mechanics have been interested in quantitative flow visualization techniques; the primary advantages lie in their non-invasive nature and in their capabilities of full-field measurements. Most of the techniques were based on photographic recording. However, recent developments in video and computers have stimulated experimental techniques.
