Schlieren photography

Schlieren photography is a process for photographing optical inhomogeneities in transparent media that are not necessarily visible to the human eye, typically used to study fluid flow, like the flow o

Shadowgraph

Shadowgraph is an optical method that reveals non-uniformities in transparent media like air, water, or glass. It is related to, but simpler than, the schlieren and schlieren photography methods that

…distort the collimated light beam. This distortion creates a spatial variation in the intensity of the light, which can be visualised directly with a shadowgraph system. Classical schlieren imaging systems appear in two configurations, using either one or two mirrors. In each case, a transparent object is…

Shadowgram of shock waves from a supersonic bullet fired from a rifle. The shadowgraph optical technique reveals that the bullet is moving at a Mach number of about 1.9. Left- and right-running bow waves and tail waves stream back from the bullet, and its turbulent wake is also visible. To the right of the frame are seen unburned powder particles from the cartridge, themselves traveling slightly subsonic so that each of them produces a curved bow shock wave.
