- Schlieren Photography. Schlieren photography (from the German word for "streaks") allows the visualization of density changes, and therefore shock waves, in fluid flow. Schlieren techniques have been used for decades in laboratory wind tunnels to visualize supersonic flow about model aircraft, but not full scale aircraft until recently. Dr. Leonard …

- Schlieren photography (from German; singular "Schliere", meaning "streak") is a visual process that is used to photograph the flow of fluids of varying density. Invented by the German physicist August Toepler in 1864 to study supersonic motion, it is widely used in aeronautical engineering to photograph the flow of air around objects.

- Schlieren photography is similar to the shadowgraph technique and relies on the the fact that light rays are bent whenever they encounter changes in density of a fluid. Schlieren systems are used to visualize the flow away from the surface of an object. The schlieren system shown in this figure uses two concave mirrors on either side of the test section of the wind …

- 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 wings of airplanes. How does Schlieren photography work? It produces well contrasted-pictures based on the difference in gas or liquid density.

- In Schlieren photography, this light source will be as tiny as you can make it, and so the projected image will be a thin line or a tiny dot. Now imagine that patch of air in front of the mirror. Any light passing through it will be refracted, but only a tiny amount, normally invisible.

- Schlieren Imaging is a way to make invisible flow elements, such as gases, air, and other transparent media visible. The recent advancements of in high-speed imaging technology have increased the quality of images possible through this technique. Increased light sensitivity, higher speed capabilities, and specialized features have contributed ...

- Schlieren imaging is a photography technique to perceive the dynamics of fluids of various densities. For a simple mechanical setup, schlieren imaging is incredibly sensitive. It is precise enough to highlight warm air rising from your hands in when you rub them together, and with this baseline, it makes striking a match look like dazzling fireworks.

- Schlieren acquisition. Now move your razor blade to intercept your focal point. If you have a way to simultaneously view the output from your camera, this will make this process easier. You want to position the razor roughly half way into your focal point, and you'll know you've gotten it right when you can see imperfections in the shape of ...
