See more Schlieren are optical inhomogeneities in transparent media that are not necessarily visible to the human eye. Schlieren physics developed out of the need to produce high-quality lenses devoid of such inhomogeneities. … See more Schlieren flow visualization is based on the deflection of light by a refractive index gradient The index gradient is directly related to flow density gradient. The deflected light is … See more • Background-oriented schlieren technique • Laser schlieren deflectometry • Mach–Zehnder interferometer See more Schlieren were first observed by Robert Hooke in 1665 using a large concave lens and two candles. One candle served as a light source. The warm air rising from the second candle … See more The schlieren effect is often used in video projector technologies. The basic idea is some device, such as a liquid crystal light valve, is used to produce schlieren distortions in a controlled manner and these are projected on a screen to produce the desired image. … See more • Background oriented schlieren for flow visualisation in hypersonic impulse facilities • Visualisation of supersonic flows in shock tunnels using Background Oriented Schlieren (BOS) technique • Video on Schlieren photographs See more WebHigh Speed Video Schlieren.
