Seeing the Invisible with Schlieren Imaging
Lekholm, Ville; Ramme, Goran; Thornell, Greger
Physics Education, v46 n3 p294-297 May 2011
Schlieren imaging is a method for visualizing differences in refractive index as caused by pressure or temperature non-uniformities within a medium, or as caused by the mixing of two fluids. It is an inexpensive yet powerful and straightforward tool for sensitive and high-resolution visualization of otherwise invisible phenomena. In this article, application of the method to liquid membranes, sonar pulses and microscopic gas flows is used to illustrate its usefulness and versatility in physics education and research. (Contains 7 figures.)
