- Schlieren photography is a technique by which the flow of fluids with varying densities can be photographed. Schlieren-style imaging techniques had been in practice long before the term was coined, but between 1859 and 1864, August Toepler rediscovered the technique and named it after the German term for optical inhomogeneities in glass . In practice, the term "Schlieren" …

- Instead, for the cost of about half of the interesting light you can much more easily block the boring light by inserting a knife edge at the focus. It only has to be placed correctly in two dimensions, and one of those, the focus dimension, is fairly forgiving. Dec 18, 2016. #4.
Schlieren Photography - Optical System

- In schlieren photography, the collimated light is focused with a lens, and a knife-edge is placed at the focal point, positioned to block about half the light. In flow of uniform density this will simply make the photograph half as bright.
SCHLIEREN PHOTOGRAPHY PRINCIPLES - Davidhazy

- The knife edge or filter array in conjunction with the image of the light source acts as a discriminator which makes visible deflected light beams. To get into schlieren photography examine this demonstration. All you need is an astronomical quality mirror of fairly long focal length preferably of spherical figure rather than a parabolic one.

- A schlieren setup is nearly identical to that of a shadowgraph but with the addition of a knife edge at the focal point of the second lens or mirror as shown in Figure4. The amount of light blocked by the knife edge is commonly referred to as \cuto ." Figure 4: …
