    Our first Schlieren Photo of a Candle Burning From what I know Schlieren optical systems let you see and photograph differences in fluid densities by using refraction of light. Refraction happens when the light passes from one medium (like air) of a given density into another medium (like water) of a different density.

    This article is a guide to understanding Schlieren photography - and ultimately doing it in your own home! Schlieren photography is essentially photographing fluid dynamics by exposing the densities of fluids by the way that light refracts through it, including hot and cold, shockwaves, or other pressure effects. This is useful for photographing everything from the thermodynamics of a ...

    Thus, schlieren photography can be used in many engineering problems such as heat transfer, leak detection, study of boundary layer detachment, and characterization of optics. beamer3.6m Posted April 12, 2016

    Schlieren photography is a technique for making differences in refraction indices in a fluid visible. A refractive index is a measure of the degree to which light passing through the fluid is bent. In my case, the "fluid" is air and the refractive differences are caused by regions of warmer and cooler air. This is…

    A few people have emailed me and asked about the setup that I use for taking Schlieren pictures. In the Site Index of Projects link there are links to all the posts that I have done explaining what I did to make the pictures. But I suppose that pictures (or videos) can speak a 1000 words as they say so I decided to make a video that shown what my setup looks like.
  6. The Schlieren effect comes out nicely, but the shadows of the physical objects are blurry. 7/27/2009 Update: I am using a different slide to color these and I like the effect a lot. The last one is trying to replicate that cough photo by Gary Settles that has been in the news. Not as good of course, since he is an expert who does this for a living.

    My post last week about shadowgraphy and Schlieren photography generated a lot of enthusiastic responses and not a few requests for a more detailed tutorial. Among the comments was one by Ian Smith, who has a great page here describing his own Schlieren photography set-up. (While you're there, take a moment to appreciate the fact that Ian's URL is "www.ian.org"….think he's been ...

    A schlieren photograph showing the compression in front of an unswept wing at Mach 1.2 Schlieren image of a shotshell projectile exiting a barrel. Schlieren photography is a process for photographing fluid flow. 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.
  9. Schlieren photography is a method where you're able to image differences in indexes of refraction of air, which basically means you can see heat and various gasses that alter light due to their physical properties. A subject is placed between the light source and the mirror, and then the disturbance is visible on the camera sensor.

    Using the technique of schlieren photography, Mach and his son Ludwig photographed the shadows of the invisible shock waves. Invented in 1864 by German physicist August Toepler, schlieren photography is, essentially, a process of photographing fluid flows by measuring the spatial variations in the intensity of a light source shining on or from ...
