The term "schlieren imaging" is commonly used as a synonym for schlieren photography, though this article particularly treats visualization of the pressure field produced by ultrasonic transducers, generally in water or tissue-mimicking media. The method provides a two-dimensional (2D) projection image of the acoustic beam in real-time ("live ...
Background-oriented schlieren technique (BOS [7]) relies on measuring or visualizing shifts in focused images. In these techniques, the background and the schlieren object (the distortion to be visualized) are both in focus and the distortion is detected because it moves part of the background image relative to its original position.
Toepler's original system [2] was designed to detect schlieren in glass used to make lenses. In the conventional schlieren system, [3] a point source is used to illuminate the test section containing the schliere. An image of this light is formed using a converging lens (also called a schlieren lens).
Synthetic schlieren is a process that is used to visualize the flow of a fluid of variable refractive index. Named after the schlieren method of visualization, it consists of a digital camera or video camera pointing at the flow in question, with an illuminated target pattern behind.
“That’s what all the great leaders do. You can’t just hammer people with how bad stuff is. You’ve got to bring some positivity and good energy to the things you think are important. That ...
When you need to make an entrance, you call Lady Gaga.To announce his arrival at the helm of Celine in 2018, Hedi Slimane enlisted the performer to tote around his first handbag for the maison ...
The early days of PIV can be credited to the pioneering work of Ludwig Prandtl, a German physicist and engineer, who is often regarded as the father of modern aerodynamics. In the 1920s, Prandtl and his colleagues used shadowgraph and schlieren techniques to visualize and measure flow patterns in wind tunnels.
Beilein met with reporters to say that he intended to say "slugs," which didn't reflect how hard they were playing. However, few seemed to accept that explanation and the Cavaliers' performance ...
