Hologram: the effects of the future have become real. Holus, Vimeo and hologram shows
Holography is a special photographic method, the essence of which is in creating a three-dimensional image of any object using a laser. The product of holography is a hologram – this is the image itself, which creates an optical illusion of three dimensions and volume. Hungarian scientist Denesh Gabor became the founder of holography, and he even received the Nobel Prize for his invention in 1971. And although Gabor made the first hologram back in 1947. The business of life of the scientist lives, and, as we know, the hologram acquires a new quality and multi-format with each new day. In particular, during the life of a scientist, only a two-dimensional image could be made hologram, and in the modern world there are already developed technologies of hologram video.
The first developments of Gabor were low quality due to the fact that in his time lasers had not yet been discovered. In 1960, red lasers, ruby and helium-neon, were developed, which in fact was the beginning of a new era in the development of hologram images. Within a few years, thanks to the development of lasers, the first hologram portrait was created. The development of the multiplex was the culmination of that time – it differed from a conventional hologram by layering various flat images from different angles, which created a more volumetric view of the hologram and the opportunity to see a hologram picture not distorted from different angles.
In our reality, there is already such a technology as a hologram video. Such a video has found the greatest popularity today in the so-called hologram shows – hologram effects are applied at events and, in particular, concerts. In addition, there are already exist channels and devices where you can watch videos of this type. If it is easier to explain, you get the impression that the video you are watching has hung in the air.
Viewing a holographic video is possible thanks to a special video playback system, for which a special reverse projection is used involving 3D content. However, other ways are being developed to play and view such videos, for example, smartphones with a specialized screen and the like. Now the creation of a hologram video or show is quite a long process. To create hologram effects for a concert you need 12 hours of installation time only.
How are holographic displays being developed and why does fog affect it?
Quite recently, we considered fiction 3D-printers or plasma TV screens. But science constantly surprises us almost daily. The development of holographic displays, that is, those on which you can view surround video, began at the beginning of the two thousandth, and already on the threshold of the 10s it has ceased to look like a distant future and unattainable fiction. About 10–15 years ago, stereoscopic technology entered our lives, which could be viewed in video mode using special 3D glasses. Next is television, which has become an inter-stage process in creating a clear hologram image that will be voluminous from different angles.
A few years ago, a special almost transparent film became popular for the so-called pseudo-hologram, which needed to be hung from the ceiling and projected onto it. At certain angles, the contours of the grid were invisible, so in fact for the viewer, an impression of a picture hanging in the air was achieved.
Approximately at the same time a fog burst into the development of a hologram video. Yes, it is the fog from which scientists have thought to form images. Such holograms can be created only indoors, because the minimum gust of wind carried the fog and it lost its shape of the image. Also, a special achievement of this technique was that it became interactive - the audience could themselves use their fingers and change the shape of the “foggy model”. For this type of creation and modeling of holograms, a specialized screen and a projector were used.
The first portable holographic display appeared in 2012. It was installed in a luxury car Lykan HyperSport. The hologram display here was needed for the navigation program – a three-dimensional image of streets and objects helped the driver to quickly navigate the terrain. Interestingly, since then the hologram has taken a prominent place in the automotive industry – for example, the world-famous Mitsubishi brand announced the development of an “air” hologram display.
In 2013, scientist Michael Bove suggested that in the next decade, holographic screens will enter the mass market and be distributed in all developed countries. As of 2013, Bove said that the world already has all the technologies to make a hologram screen cheap, portable and accessible to people.
What hologram technologies exist in the world today?
Today, the world knows four hologram technologies: laser, electro-hologram, parallax and MEMS. In a few words we will get acquainted with each technology that has been developed and studied from the 60s of the last century to the present.
A hologram created with a laser is the first and still most popular technology in the world. A laser is used as the light source, which is then reflected to the recording device. Part of the laser also shines on the selected area of the display.
Electro-hologram – created using a special display that transmits data about stored images using an electromagnetic resonator. From the basic electro-holographic displays are distinguished by enhanced image clarity and color depth.
Full parallax – due to image quality from all angles, is most often used at concerts and in cinema. Full parallax consists of vertical and horizontal parallax – VPO and HPO (vertical parallax only and horizontal parallax only). These are the parallax components, with the use of only one of them, the hologram ensures the delivery of optical information in only two dimensions.
MEMS – this technology allows holographic displays to include very small moving parts in their design.
Holus display bursts into people's lives
As we have said, in 2013, Michael Bove noticed that soon holographic displays would become the subject of a mass market, and two years after the proclamation of this thesis, Canadians decided to support him. In 2015, the Canadian startup H+Technology introduced the display to the world, which itself may well become a must have in several years to come.
Holus – as the creators called it – is a unique hologram display in the form of a pyramid, portable enough and small enough for placement in the home. This is a kind of desktop platform that can display a holographic image and video from any smart gadget that you have at your fingertips. Using a control from a gadget to which a prism is connected, Holus can display any digital content from a tablet, smartphone or PC in the form of a hologram.
The display has the approximate dimensions of a microwave oven, inside it is placed a Plexiglas prism with a special coating. The projector under the cover of Holus projects the image on the four walls of the prism. Regardless of how many people look at the display and from what angle, a holistic hologram image appears in the center of the prism, and if a video is played, then the moving image.
On the market, Holus is available in two versions of Pro and Home Simplified. Of course, the first is somewhat more expensive, at the time of its release in 2016, the cost of the device fluctuates around $ 900. Over time, it is possible to develop a connection between a prism and a gadget via Wi-Fi and Bluetooth. And the cheaper and more common the applied technologies will become, the more accessible the device will be for mass purchase.
Vimeo launches channel for viewing holographic videos
Vimeo never ceases to delight us with its innovative views. Vimeo once again pleased users with an extraordinary service and announced the launch of a channel to view hologram videos. Of course, for this you will need to purchase a special device with a holographic display, the price of which today fluctuates around $ 500 - there are even models about 400 dollars, and in the highest price segment there are 600-800.
By the way, such an announcement can significantly worsen the affairs of their most famous competitor Youtube. After all, the hologram and three-dimensional image as a whole is already displacing ordinary video from the market, and the percentage of three-dimensional video is becoming really serious today, despite the still fairly small distribution of hologram displays in the world. Soon, specialists from Youtube will have to either give first place in the market to other hands, or develop something equally impressive.
So, the hologram today is developing at a frantic pace and it is quite possible that it will oust the usual video from the market. People are willing to pay for the quality of three-dimensional image, which until recently we have only seen in the Star Wars saga. The amount of money that flows into the development of projects based on the development of holograms is evidenced by the fact that Holus developers collected the necessary amount for their startup in 18 hours, and a few days later they received funds that almost tripled the amount they needed to start developments.
A hologram is really being prepared to make a habitual phenomenon in everyday life, and the further we learn about new developments, the less fantastic the thought of a hologram connection or X-ray seems. Such technologies can not only provide an entertainment component in human life, but also become leading in medicine, engineering, communications, military affairs, and so on.
