Transcript of Holograms
Mike Roman Holograms History How It Works Original Hologram pattern is displayed on a small LCOS microdisplay Light Blue Optics' proprietary "hologram chip" Illumination through Laser Light Where's It Going? Used for business adverting and is coming to the average consumer.
Liti Holographics has made a tremendous breakthrough in holographic technology.
Produces holograms in a fraction of the time previous required.
Can offer custom holograms directly to individuals.
As a result, Liti3D brings holograms directly to the average consumer.
Technology and cost has never been seen before.
Another very well-known company is telepresence, which has succeeded in creating holographic conferencing techniques.
Creates a virtual conference where people can actually record themselves and be on stage.
Holographic TV is also coming closer to reality.
It shows three-dimensional displays with memory, something necessary to create 3-D images.
With the release of 3-D television and the popularity in 3-D full length feature films, it is only a matter of time before holography comes into play through a televised program.
Holograms (or Holography) developed in 1947
Holography coined from Greek “Holos” (whole) and “Gramma” (message)
Creator Dennis Gabor realized the science was ahead of its time.
Could only create holograms on film transparencies that used mercury lamps for viewing. Technology barrier broken by the invention of the laser in 1960
Holographic portraits were the first products created with the laser. High brief pulses of light froze images at high speeds, creating 2-D holograms.
First 3-D hologram in 1964, created by Russian scientists after studying Gabor’s research. What is a hologram? -Scattered light recorded and later reconstructed to appear.
-Change in position allows for 3D
-Stores and retrieves information
Price -Projectors are anywhere from $300-$5,000.
-Projector bulbs are also $300-$600 and need replacing.
-Some companies are offering miniature holograms for under $100 Today's Uses Today, many products use holograms in order to function, such as:
Supermarket checkout scanners
theme park attractions
Interactive Holograms In 1962 Russian scientists created white-light reflection holograms, which no longer required special viewing lamps.
Holographic television experiments led to white-light transmission holography, a type of hologram visible underneath ordinary white light. This led to mainstream holography in print media.
Holographic television research continued. In 1972 internal holograms were developed. They combined cinematics and holograms to make 3-D images.
The first holographic movie created in Russia: special cameras pulsed holographic images, and displayed on a special screen. The movie was 47 seconds long, other attempts for longer movies were failures. Works Cited http://www.holophile.com/history.htm
