A holographic display is an object that uses holographic projection to project an image to a specific area such as a television screen, or a wall or even a mirror. A hologram is essentially a computer generated image of a diffraction pattern that uses diffraction in order to create an image that still has all the properties, depth, parallax, and other characteristics of the real scene. Holographic holography is the art and science of creating holograms in an optical state of mind. The science of holography has been around for hundreds of years but is only recently becoming more popular.

This type of holography can be done with a digital camera that uses a holographic lens. The holographic lens consists of two small spherical lenses that are placed in opposite directions that are exactly aligned so that when the two lenses are put together, they form a single hologram. When this happens, each and every point on the hologram will be reflected onto the object of interest. These holograms are then combined to form a computer generated image of what it was that the hologram was intended to do. In some cases, these holographic holograms are then combined with video and sound in order to give the viewer the illusion that what they are seeing is a true life experience.

Holographic holography can be done using several types of lasers and the process of combining the lasers to create the final image depends on the type of laser used. A hologram created with a laser such as a black hole or a high-energy electron-laser (HEL) works best for images or pictures with a higher degree of resolution. For images that have less resolution, holographic holography with a Compacted Holographic Emitter (CHE) laser are best. Hologram holography is used for applications in communication, security, military, scientific research, etc.
