3D Holographic Technology

3D holographic technology is a technique of scattering light to present an image that appears to the eye to be three dimensional. The image is an attempt to record a picture of an object and reconstruct it so the viewer can see different angles. The technology is most commonly used on flat surfaces to create images for security and authentication purposes.

History

·         The basic technology of holography was discovered in 1947 by Dennis Gabor, a Hungarian physicist working on advancement research for electron microscopes. However, the technique was not fully utilized until the 1960s, when laser technology was perfected. 3D holographic technology was created in 1962 by scientists in both the United States and Soviet Union.

Types

·         There are a variety of holograms. Transmission holograms require the light from a laser to be shined through the opposite direction of the viewer to create a 3D image. Rainbow transmission holograms use the same technology; however, the light source can be monochromatic or white. The reflection hologram can be used to present a 3D image using a light source on the same side as the viewer.

Advances

·         3D hologram technology has advanced notably since the 1980s owing to low-cost solid-state lasers that became prevalent for consumers in devices such as DVD players. These lasers can be purchased by a small company and used to create 3D holograms for a variety of uses. Previously, lasers needed to be large due to the gas chambers necessary for them. This made the devices accessible only to major companies and scientific divisions.

Features

·         The way 3D hologram technology operates is by creating the illusion of three-dimensional imagery. A light source is projected onto the surface of an object and scattered. A second light illuminates the object to create interference between both sources. Essentially, the two light sources interact with each other and cause diffraction, which appears as a 3D image.

Common Uses

·         3D holographic technology is used in a variety of ways in modern society. The most prevalent use of the images is for credit cards. Small holograms are added to cards to prevent security violations. Many packages utilize small stickers on boxes to guarantee the product is authentic. Collectibles and artwork also commonly use holograms. Trading cards sometimes release holographic versions for collectors. Laser artists also use holograms in a variety of ways.

It is really incredible technology. Look at the first video the women was in Chicago but she was appearing in USA. In the future we can meet each other from our home. What I mean by that I mean the business man can do many meeting from one place to accept and save the time. Also, if the teacher busy he can teach us by this technology.

  

It will be used in King Abullah economic city in Saudi Arabia. Look at this video and the man who was standing on the stage was appearing by this technology
