A hologram is an image created by a photographic projection of a recording of a light field rather than an image formed by some sort of lens. It appears as a three-dimensional representation on a two-dimensional object, which can be seen without intermediate optics such as goggles or glasses.
Dennis Gabor, a Hungarian-born scientist, invented holography in 1948, for which he received the Nobel Prize for Physics more than 20 years later (1971). Gabor considered the possibility of improving the resolving power of the electron microscope, first by utilizing the electron beam to make a hologram of the object and then by examining this hologram with a beam of coherent light. In Gabor’s original system the hologram was a record of the interference between the light diffracted by the object and a collinear background. This automatically restricts the process to that class of objects that have considerable areas that are transparent. When the hologram is used to form an image, twin images are formed.

Microsoft HoloLens, under development as Project Baraboo, is a pair of mixed reality, smart glasses developed and manufactured by Microsoft using the principle of Hologram.


It is available in India and its price is $3000.

This Technology has been given the future of Mixed Reality. Imagine getting step-by-step instructions on things like home repair from an expert. Visual diagrams would actually show up in space around the user indicating exactly what you need to do next. This application could even extend to the battlefield, where detailed medical instructions could be given to untrained personnel in the midst of combat.
