three dimensional properties of holographic images make holograms ideal for displays. Holography can produce spectacular displays for scientific, educational, medical, artistic and commercial purposes. Holographic displays would avoid the risk of theft of art objects. The same object can be displayed at several places at the same time, thus permitting much wider exposure of rare items. This type of hologram is recorded on to a photographic glass or film plate. The photograph of a virtual object reproduces real 3D magic in display hologram. Display holography is basically a large-scale holography which can play a vital role to get the impact and attention you have been seeking.
Properties of Display Holograms
Display holograms have certain characteristics like as follows:
Â¢ Extreme plastic representation
Â¢ Availability in various sizes starting from a small stamp size image to the size of an entrance door or even more.
Â¢ High artistic value
Applications of Display Holograms
Display holograms are widely used in the following:
Â¢ 3D Poster & Display
Â¢ Store Fronts
Â¢ Science Centers
Â¢ Reproduction of Museum Exhibits and Archival Artifact
Â¢ Recording, Artistic Development & Teaching
Â¢ Educational Institutions
Â¢ Public Spaces
Â¢ Product Enhancement
Â¢ Pop-up Display
Â¢ Sales Presentation
Â¢ Celebrity Product Endorsement
Â¢ Mixed Media Display
Â¢ 3D Portraiture: VIPs, Gods, Family, Celebrities, Children, Wedding
Â¢ Trade shows
And there is another advancement in hologram display is 360 degree 3D holographic display which is made by made by Using a spinning mirror covered with a "holographic diffuser," a special DVI implementation, and a high-speed project and implimentationor, the device can project and implimentation a three-dimensional image that can be viewed from 360 degrees -- regardless of the viewer's height and distance.
Display holograms are widely used as tool wherever an audience needs to be reached. They are popular and used frequently for eye-catching displays at trade fairs or presentations-a truly unique and amazing way to present objects, corporate images, educational materials and many more like art images hanged over the wall

A hologram is a type of three-dimensional image that gives the appearance as a real object as the image has depth. The best way to think of a hologram is to visualize them as impressions on light waves. The patterns of light wave impressions are photographed or captured in the layer of emulsion. In other words, a hologram is an image or photograph of light wave interference. It is to be noted that not all 3D images are holograms and neither a hologram is required to be 3D. In technical terms, a hologram is the captured intensity and phase information which is produced by the interference or interconnection of two or more beams of light. People often consider a hologram as some type of a three-dimensional photograph. However, the only thing common between photography and holography is the use of a photographic film. The important difference is the way the image is produced in both the cases. A photographic image is produced by a camera lens and it is described almost accurately using a simple geometric or ray model for the behavior of light. On the other hand, the holographic image is formed depending on diffraction and interference, which are wave phenomena.
Holograms have some very interesting properties such as follows:
• Distributed information: The information in a hologram is always distributed. If it is cut into pieces, each piece contains enough information to reconstruct the entire scene.
• Image project and implimentationion: Under certain cases, merely shining or lighting a laser through the hologram project and implimentations an image on to a screen.
• Viewing directly with a point source: A hologram reconstruction shows exactly the same light wavefronts to our eyes that we receive with the real object, using a point source of illumination. The hologram is not distinguished from the physical object.
