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.
Microsoft Excel is a spreadsheet editor developed by Microsoft for Windows, macOS, Android, iOS and iPadOS.It features calculation or computation capabilities, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications (VBA).
These are visualized by optical methods known as the shadowgraph, schlieren photography, and interferometry. More directly, dyes can be added to (usually liquid) flows to measure concentrations; typically employing the light attenuation or laser-induced fluorescence techniques.
Shadowgraphy (performing art), using hand shadows; Shadow play or shadow puppetry, performing art using cut-out figures; Radiography, the use of X-rays; Shadowgraph or shadowgram, an optical method that reveals non-uniformities in transparent media; Optical comparator, a device that creates silhouettes of manufactured parts for inspection
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.

Scene with shadow mapping Scene with no shadows. Shadow mapping or shadowing projection is a process by which shadows are added to 3D computer graphics.This concept was introduced by Lance Williams in 1978, in a paper entitled "Casting curved shadows on curved surfaces."
The profile projector is widely used for complex-shape stampings, gears, cams, threads and comparing the measured contour model.The profile projector is hence widely used in precision machinery manufacturing, including aviation, aerospace industry, watches and clocks, electronics, instrumentation industry, research institutes and detection metering stations at all levels, etc.
