Perhaps the most surprising thing about shadowgraphs is how simple they are: you simply take a point source of light, pass the light through a the volume of air to be imaged, and record the pattern ...
Schlieren imaging techniques have emerged as a powerful diagnostic tool in fluid dynamics, providing detailed visualisations of density gradients and refractive phenomena in transparent media. By ...

Air density probably isn’t something you think about every day. Well, thanks to the Schlieren effect there’s now a reason to do just that. After being discovered by German scientist August Toefler in ...
The photographic technique known as Schlieren photography gets its name from the German word "Schliere", meaning "streak". It was first developed to visualize the airflow around objects such as the ...
The photograph was taken in the exact moment when the pilot transitioned from subsonic to supersonic speed. The photograph in this post shows a U.S. Navy Lockheed Martin F-35C Lightning II of Air Test ...
Researchers at NASA have reinvented an over 100-year-old photography technique to capture the shock wave generated by a new supersonic jet. The image will be created using the sun as the background.
The airborne spread of pathogens has assumed great importance in the public eye following the onset of the coronavirus disease 2019 (COVID-19 pandemic). In an interesting new research paper published ...
NASA has successfully tested a new technique that will prove its planes can fly faster than the speed of sound without producing a sonic boom, potentially halving current commercial flight times. The ...
