The shadow map is An optical method to reveal inhomogeneities in transparent media Such as air, water or glass. It is related to schlieren and schlieren photography methods that perform similar functions, but are simpler than them. Shadowgraph is a flow visualization.

What is a shadow map in engineering?

The shadow map is An optical instrument that reveals inhomogeneities in transparent media such as air, water or glass. While temperature differences, shock waves in different gases or transparent media cannot be seen directly, all of these disturbances refract light so they can cast shadows.

What is the schlieren test?

The schlieren system is Used to visualize flow away from the surface of an object. The Schlieren system shown in this figure uses two concave mirrors on either side of the wind tunnel test section. Mercury vapor lamps or spark gap systems are used as bright light sources.

What are the advantages of optical comparators?

Advantages of Optical Comparators

• High precision is possible due to very few moving parts.
• Lighter weight than other comparators due to fewer parts.
• Parallax errors will be avoided.
