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 perform a similar function. Shadowgraph is a type of flow visualisation.
Particle image velocimetry (PIV) is a non-intrusive optical flow measurement technique used to study fluid flow patterns and velocities. PIV has found widespread applications in various fields of science and engineering, including aerodynamics, combustion, oceanography, and biofluids.
If a knife edge is not used, the system is generally referred to as a shadowgraph system, which measures the second derivative of density. In the two-mirror schlieren system (sometimes called the Z-configuration), the source is collimated by the first mirror, the collimated light traverses the object and then is focused by the second mirror ...
