3D holographic technology has been increasingly applied in the areas of advertising, media, and fashion. Many technology companies are also planning to use this technology to develop displays for electronic devices. What is 3D holographic and how does it work?
3D Holographic technology
1. What is holographic 3D?
Holographic is a technique that allows light to scatter from a recorded object and then reproduce the 3D image in a laser beam. Thus, the image of this object will be seen even if it is no longer present at that location. The purpose of this technology is to create a 3-D image floating in the air without the need for a screen, allowing the viewer to observe the 360-degree image without using any type of spectacle lens. Floating image demonstration is made possible by a high resolution-projector, a background generator, and a rendering component.
2. Origins of 3D holographic technology.
The holographic 3D technology was invented by Hungarian physicist Dennis Gabor in 1947. The original technique invented by the physicist was still used in electron microscopy but developed in another direction when the development of the laser. In 1962, Yuri Denisyuk of the former Soviet Union and Emmett Leith and Juris Upatnieks of the University of Michigan in the United States used lasers to project three-dimensional optical imagery to create the first 3D images. Since then, 3D holographic technology has continued to grow and is now widely used in the field of monitors for electronic devices.
3. How does 3D holographic technology work?
- In order to create 3D images, an HD projector, a base unit, a video file is required for 3D projection, a laptop to operate the projected image, and a space with dark colors and light fitting.
- Image from the laptop when projected through the direction of the audience, through the background generator will show the viewer will look like 100% real image. This technology is purely virtual background image that users can go through, or use the unique effects to dissolve the image.
- To create beautiful and realistic effects, 3D background images are rotatable images, with dark background and high contrast. The simpler the image, the more illuminated the better the effect of the design complex.
3. Application of 3D holographic technology for 3D TVs.
- With Holographic 3D technology, the viewer not only perceives the depth or effects of the subject as 3D TV or 3D screen. This technology allows viewers to view images at 360 degrees. The objects that appear on the screen will give the viewer the same feeling as watching the actual object appear before the eyes. The demonstration of the stereoscopic image was done by a high resolution projector, a background generator and a rendering component.
- Currently, 3D Holographic is still being developed and applied in some special fields such as defense, military. Engadget said the company recently named Zebra Imaging has just launched the first commercial holographic 3D screen size 30 x 45 cm at a price of 1,500. This will be the premise for this 3D rendering technology soon to complete and popular in the future.
Nowadays, 3D holographic projection technology is widely used in advertising shows, fashion shows, technology, music stages etc. to impress the viewers. In the future, we may use TVs with 3D holographic technology which is absolutely better than now.
