Holographic display is a portrait, image or a design with a 3D effect, reproducing a virtual sensation of real objects. It attempts to present the user with a realistic scene. The realism involves the use of depth cues. Portraits on the display can be of God, celebrities, family, children, wedding, etc. It can also have some artistic designs, scenes of gardens, space, museum, etc.

Types of Holographic Display
Holographic display can be of the following types:

• Stereoscopic Display- A display system that gives a 3D effect with the help of an external aid like glasses.
• Autostereoscopic Display- A display technology that can produce truly 3D images that look as good as the actual 3D objects and scenes.

Technique of applying Holographic Display
Fill a tube with three noble gases that are non-reactive with each other and the tube material. Each gas must respond to a laser wavelength with that particular color. Then, take three lasers and split each beam in a holographic style and fire one beam of each straight into the tube. The other half of the beam sets up interference patterns according to the information it gets from the data source. The data source can be a computer with super duper 3D card or live holographic camera. The interference pattern thus formed shows up a moving or still 3D picture.

Applications
They are widely used for interactive graphic application. Typical applications include posters, pop-up displays, product enhancement, sales presentation, mixed media display, and celebrity product endorsement.
