Talking about 3D hologram technology, what comes to our mind is only in films and not in the real world. In fact, scientists from the University of Arizona have developed a technology where one day can be used to store large amounts of data in holographic form. According to one scientist Nasser Peyghambarian, Hologram optics will offer future applications in medicine and manufacturing as well as in the entertainment industry. The research team from the University of Arizona has announced that they have succeeded in developing the fastest 3D hologram movement.

Nasser Peyghambarian was one of the scientists who discovered this 3D Hologram Technology. He said that “Technologies such as direct communication with holograms seem to exist only in film. And we are scientists trying to bring it out into the real world, “he said, as reported by Nature. “But now we have shown that creating a dynamic hologram of size and resolution as in film will become a reality,” he added.

Holograms are products of holographic technology. The hologram is formed from a coherent combination of two rays of light and in microscopic form. The hologram acts as an optical information warehouse. Optical information will then form an image, scene, or scene. A hologram is an incarnation of the latest information storage. The advantage of the hologram is that it is able to store information, which contains 3D objects. Not only objects that are usually found in photographs or pictures in general. That is because the working principle of a hologram is not as simple as a photographic lens. Holograms use the principles of diffraction and interference, which are part of the wave phenomenon.

That is because the working principle of a hologram is not as simple as a photographic lens. The hologram uses the principles of diffraction and interference, which are part of the wave phenomenon. The characteristics of a holographic hologram, have unique characteristics. Some of them are: Light, which reaches the eye of the observer, which comes from the image reconstructed from a hologram is the same as if it came from the original object. A person, in looking at holographic images, can see depth, parallax, and various different perspectives as there is in the actual landscape scheme. The hologram of a scattered object can be reconstructed from a small part of the hologram. If a hologram breaks into pieces, each parts can be used to reproduce the whole image again. However, shrinkage of the size of the hologram can cause a decrease in perspective of the image, resolution, and brightness of the image.

From a hologram can be reconstructed two types of images, usually a real picture (pseudoscopic) and virtual image (orthoscopic) A tube hologram can provide a 360 degree view of the object More than one independent image can be stored in one photographic plate that can be seen from one one at a time

The hologram sticker is a type of seal and label for product security because in it is embedded with high-level security technology, in making hologram stickers can not be made with ordinary printing machines such as most printing stickers that are on the market. For example making ordinary seal stickers is enough to use film master thin sheet of zinc.

Actually we have felt the application of this technology together, the example is when we watch 3D movies in the cinema using 3D glasses that add light effects. Only me these glasses are just projecting images with the help of light effects, another example is a product from Google, Google Hololens. Google Hololens is an AR eyeglasses projecting a digital display there is a glass screen with 3D effects so that the display appears to be in real space.

No wonder that in a few years this technology will begin to be used in everyday life. Not only in the field of technology, but also in the fields of medicine, entertainment, and other fields will also be affected. In this era of rapid technological development, just waiting for the day to feel the technology.

In addition, holograms can also be applied in the general public environment, for example 3D holograms can be used to send or present objects or people without having to be imported directly. Objects or humans that are presented are also in 3D, so it looks real. Primsipnya is to record what we want to convey, then processed using this holographic technology. After data processing occurs, the object or whatever we record is able to be present without having to be attended directly by the object or person concerned. 3D hologram technology is very helpful a variety of human needs today. Busyness and high mobility can be overcome with this telecommunications technology.

Hologram Characteristics

• Light, which reaches the eye of the observer, which comes from the image reconstructed from a hologram is the same as if it came from the original object. One, in looking at holographic images, can see depth, parallax, and various different perspectives like those in the actual landscape scheme.

• The hologram of a scattered object can be reconstructed from a small part of the hologram. if a hologram breaks into pieces, each piece can be used to reproduce the entire image again. However, shrinkage of the size of the hologram can cause a decrease in perspective of the image, resolution, and brightness of the image.

• From a hologram two types of images can be reconstructed, usually pseudoscopic and virtual images (orthoscopic).

• A tube hologram can provide a 360 degree view of the object

• More than one independent image that can be stored in the same photographic plate which can be seen from one at a time

The advantages and disadvantages of holograms

DEFICIENCY

• Communication can be directly without limits because distance constraints can be overcome easily.

• Facilitate mass media, especially electronic mass media in conveying information.

ADVANTAGES

Holographic technology on television in a certain period of time can cause nausea, eye pain, dizziness & risk for pregnant women. This is because holographic television uses a lenticular lens which causes the appearance of the right and left eyes. However, this can be avoided if the hologram screen does not use a lenticular lens, but instead uses only one optical system so it will not cause nausea, eye pain & dizziness because the right and left eyes receive the same image.
