Hologram TV and 3D Holo Television
We have recently seen a television programs of two American "news" casters during which no reporter was physically present in the studio. It was actually just holograms of journalists and TV presenters that were projected as real life figures. Ever since that day, the holographic technology has been under the spotlight, and looks set to be the movie ad entertainment format of the future, especially after the recent explosion of 3D TVs.
So what is a Holographic TV?
Holography is a technique that allows the complete recording and playback of an image (it shows all the information, including information regarding the distances). Holography is an optical method to record the movement of an object on a photosensitive flat plate and rebuild the object in 3D. The Hologram technology will eventually be used for film and television and available to the consumer as a complete hologram TV experience.
History of Holographic Technology
Holography, in theory dates back to the Anglo-Hungarian physicist Dennis Gabor in 1947. After an unsuccessful attempt to improve the resolution of the microscope he was able to copy an object with a new dimension. However this idea of digital hologram technology was first proposed by JW Goodman and RW Lawrence in 1967 in an article called Digital Image Formation From Electronically Detected Holograms. . Both men, however, recorded the hologram on a photographic plate, but the sample was taken digitally. It was not until 1994 that U. Schnare and W. Jüptner spoke of complete digital holography (with recording and digital reconstruction), with the introduction of a CCD camera as a recording medium. In recent years, thanks to advances in computers and digital cameras, the move into digital holography has allowed further development of the holographic TV. We have watched the Hologram technology evolve into motion and now taking the shame of Hologram TV.
Holographic TV or (Holo TV) is the next generation 3D TV technology ready to take the entertainment by storm. A common complaint that has been raised by users of traditional 3D TV is that 3D TV's work in an unnatural way. When we view objects in the real world our eyes will converge towards the point of focus. When you watch 3D TV although we can see the objects in front on the screen our eyes will continue to focus at one point of the display and critics claim that this can lead to eyestrain and possible headaches. To overcome such problems there is now a new way to watch 3D images; that is with the use of Holo TV. Although the Holo TV is in its infancy there is already the ever growing optimism that holographic TV is the future of reality entertainment.
Holo TV can work not only with computer images but it also works with movies recorded in 3D TV mode. When viewed the Holo TV does look very realistic and 3D Holographic TV uses the same principle as holographic photos which can only be seen in fancy displays and exhibitions. The images stored on film and displayed in the form of very detailed interference patterns which one to form the correct image when the viewer views of the image from a specific angle. The beauty of Hologram TV is the fact that the image can protrude in and out of the screen whilst being viewed without any eyestrain problems. Some of the latest Holographic TV models display the 3D images in accordance with the direction in which the eyes of focusing on. The systems track the movement of the eyes to place the images in the correct position.
Holographic TV is designed to generate a very convincing image and hence TV manufacturers are now focusing their attention on further developments of the Holo TV. As time moves on we will watch Hologram TV find a firm place in our homes for the future of entertainment. In fact Hologram TV will open up endless possibilities in the field of entertainment
