Shadowgraph Wikipedia

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.. In principle, we cannot directly see a difference in temperature, a different gas, or a shock wave in the transparent air.

SHADOWGRAPH TECHNIQUE Thermopedia

The shadowgraph is the simplest form of optical system suitable for observing a flow exhibiting variations of the fluid density. In principle, the system does not need any optical component except a light source and a recording plane onto which to project the shadow of the varying density field ().A shadow effect is generated because a light ray is refractively deflected so that the position
