“A hologram that’s done right really makes you feel you’re there—that the thing is in front of you.”

Michael Klug, chief technology officer and co-founder, Zebra Imaging.

A hologram (pronounced HOL-o-gram) is a 3-Dimensional image, created with photographic projection. The term is taken from the Greek words holos (whole) and gramma (message). Unlike 3-D or virtual reality on a two-dimensional computer display, a hologram is a truly three-dimensional
In recent era hologram technology is a most trending technology used by many advertising companies to advertise their product and in medical sciences its use to teach the medical student so they can practice in virtual environment.
Previously there are many holographic project and application already made by many graphics designing companies like Project Blue Beam is a conspiracy theory that claims that NASA is attempting to implement a New Age religion, a glass or plastic sheet pyramid shape which show three dimensional objects inside it when placed on screen like PDA, Stage Performance Holograms – MDH original patented 3D holographic projection system and it was first installed at the Swarovski Museum in Austria in 1996, AtmosFx Company created a projector that creates 3D effects on your wall, or any other thing, Australian company Euclideon has created the first real multi-user hologram table in the world, Laser-plasma Holographic uses the plasma emission phenomenon of focused laser light by controlling the position of x, y, and z axes, it displays real 3D images constructed by dot arrays in the air, 7D Holograms is the future concept of 7D virtual object view in real world.
Australian, Ukrainian and Israeli military forces, and now the US military is also finding a use for Microsoft’s most advanced technology Microsoft’s HoloLens hologram headset systems are already being used in the Geographic intelligence, Holography could also revolutionize medicine, as a tool for visualizing patient data while training students and surgeons, Artists became involved with holography about as soon as it became a practical visual process, Holograms are complex optical devices and difficult to make, which gives them an incredible advantage in the commercial security market.
