Illustrates some applications of holography?
Applications of Holography
Holography can be put to many of uses other than recording images. Holographic data storage is a procedure which can store information at high density into crystals or photopolymers. The capability to store huge amounts of information in some type of media is of great significance, as many electronic products include storage devices.
Security holograms are very complicated to forge since they are replicated by a master hologram that requires expensive, particular and technologically advanced tools. They are also utilized in credit and bank cards and also quality products.
Holographic interferometry is a procedure that enables static and dynamic displacements of objects along with optically rough surfaces to be measured to optical interferometric precision (that is to fractions of a wavelength of light). This can also be used to distinguish optical path length variations into transparent media that enables, for illustration, fluid flow to be visualised and analysed. This can also be used to produce contours representing the type of the surface.
UNIFORM ACCELERATION: If velocity of a body alters by equal amounts in equivalent intervals of time, then the body is said to have uniform acceleration. OR If average a
