This is a Video I have make mini 3d hologram generator with show many 3D objects I have done my projects design 3D visualization and you can watch 3d videos without glasses.
some more information about hologram technology in the world mentioned.
1) What is a hologram?
Some fairly detailed articles are translated but not yet clear. Tatute synthesized after a relatively detailed study of what “hologram” should be translated as follows
Hologram is a product of 3D recording technique called English Holography. Holography is derived from the Greek origin which consists of two words “holos” meaning whole or whole, “graph” which means the recording.
In the narrow sense: Hologram is a flat image that, thanks to the arrangement of details so that they reflect light appropriately, emerges as a deep picture (3-dimensional image). Occasionally, these images are displayed in bookstores. The current anti-counterfeit stamps in our country also apply the principle of hologram image: When looking at this stamp under different angles they appear different colors or details.
In broad terms: Holograms are projections in which one can observe objects in any angle as if they were there, though we can not touch them. In some cases, a hologram is translated as a whole picture.
Understand in another way: Holography is a method of reproducing a 3D image of an item through a 2D (2D) flat record. Look at the two-dimensional eye record at the right angle and in the appropriate light we will see the three-dimensional image of a real thing without the presence of the real thing there. Holography is a three-dimensional world recording technique for two-dimensional environments and this two-dimensional environment can reproduce three-dimensional images of real objects.
Dr. Dennis Gabor (Hungarian-Hungarian) invented the Holography technique in 1947 in England. This invention has profound effects on many aspects of social life. So in 1972 he was awarded the Nobel Prize in Physics.
There are many different inventions and advanced recording techniques so there will be many types of holograms:
– Hologram (transmission hologram): Usually viewed under laser light coming from the opposite side of the eye compared to the hologram position.
– Hologram reflects white light (white ligh reflection hologram), the image of the object can be seen in the natural light and light from the electric lamp.
– Mutable channel hologram: You can see two or more images when looking at different angles.
– real hologram …
2) What is holographic 3D?
Holographic Technique is a unique technique that allows light to scatter from a recorded object and then reproduces the 3D image in a laser beam. Thus, the image of the object will be seen even if it is no longer present at that location.
The purpose of this holographic technology is to create a 3D image that floats in the air without the need for a projection screen, enabling the viewer to observe the 360 degree floating image without the use of any specialized glasses. brain.
Floating image demonstrations were made thanks to a high resolution projector, a grounding machine and a rendering unit.
The holographic 3D (Holographic) imaging technology was invented by Hungarian physicist Dennis Gabor in Hungary in 1947. The original technique invented by the physicist was still used in electron microscopy, but Developed in a different direction when the development of lasers.
In 1962, Emmett Leith, Juris Upatnieks (University of Michigan USA) and Yuri Denisyuk of the former Soviet Union used a laser to project 3D images to produce the first 3D images. Since then, 3D Holographic technology has continued to evolve and has widespread use in the field of displays for electronic devices. 2015, 2016
3) How 3D Holographic works
In order to create the needed hologram image, a number of simple devices are available:
Edited images are suitable for 3D projection
A stage is set up with dark colors and appropriate lighting
DVD player or laptop to operate the projected image
The image from the screen as it travels through the projector will direct towards the viewer, passing through the generator will display in front of the viewer will look like 100% real image. This is a virtual image so users can go through, or use unique effects to dissolve that image.
In order to create beautiful and realistic effects, 3D images should be multi-dimensional images, with dark background and high contrast. The simpler the image, the more illuminated the better the effect of the design is complicated.
Currently, the holographic 3D projection technology is widely used in advertising shows, fashion events, technology, music stages etc. to impress the viewer.
