For holograms the future. At least in this, the filmmakers of Hollywood, filling their fantastic films by translucent interfaces floating in the air. It seems that those were on space ships in the "passengers" and "avatar".
True, while we can see three-dimensional graphics only on movie screen, using 3D glasses or. But the startup of the Look Glass from Brooklyn created a device that brings us to a full-fledged 3D reality without using additional gadgets.
Take a look at it. It may seem that you are just a glass aquarium in which the incomprehensible red thing is located. But in fact, this is a display, and the subject is inside - the picture drawn them. The Looking Glass uses innovative technology: it creates 45 different images of the same volumetric item illuminated at different angles, and then combines them, passing through a special holographic lens. As a result, it seems that you see a real three-dimensional object.
Such a device will be incredibly useful for the creators of 3D graphics, game developers, industrial designers and engineers. The Looking Glass is compatible with software such as Maya, Zbrush, Blender, TinkerCAD and SolidWorks. It allows you to consider the results of your work right in the process. And besides, with the image you can interact as with a conventional material thing. To do this, you can connect the manual tracker LEAP Motion Controller, the Intel RealSense chamber or the game controller, such as Joy Con from Nintendo.
In the future, such technology can be popular both among gamers and ordinary digital content consumers. Agree, it would be interesting to play for something or watch movies on this screen. With Looking Glass in order to consider the action from some side, it will be enough to simply transfer to another corner of the room.
To work the display, you will need a computer with a processor not lower. Intel Core I5, 4 GB and graphic card NVIDIA GTX 1060 minimum, as well as with HDMI port for displaying the picture and USB-C to power. The display will be produced in two sizes: an 8.9-inch model for $ 600 and a 15.9-inch for $ 3,000.
You can purchase a smaller version of The Looking Glass on Kickstarter for $ 400. Approximate delivery time - December.
One of the applications of holography has become a visual holography. This attempt to comprehend some form or objects, displaying them in three-dimensional form. Artists always tried to display three-dimension in their work. Human eyes are very interesting to perceive the volume, and therefore, for a person, a three-dimensional object was always a distinctive element from the fine row. But all artificial images created by a person were two-dimensional. There is still a sculpture, but it's just a three-dimensional item. And the creation of the illusion of three-dimensionality was a dream. And then they began to develop areas that are now called stereo photography, or a multi-tech photo, where you can look at the subject and see its volume.
Unlike these areas, the hologram immediately registered three-dimensional images. It is very natural for her. Holographic exhibitions in the 1970s were very popular. Many people came, queues stood with us, and in Minsk, and in the United States. There were anchlags to see aRT HOLOGRAPHY. - Fine holography. The saddest limitation of this process was that it was impossible to transfer the dynamics in these three-dimensional paintings.
Scientists tried to invent animation techniques when writing holograms. And microcoo appeared, where it was possible, moving near the hologram, to see how the object develops, which was recorded on this hologram. For example, blooming flowers: if they remove them with a hologram with a certain interval, then, after moving the flower development process in space, you can see a three-dimensional picture of how the flower changed in time. That is, the move towards Movie-holographic existed always. But a person would like something similar to the TV, because everything is already accustomed to him.
Electronic information display means allow you to change the picture very quickly. It is very democratic because they are not so expensive. And the holographic movie turned out to be very expensive. Equipment for display - all this was very difficult. And here there is such a problem: there are no registering media for dynamic holography. And some of the results of the search for these environments have now been mediated in the area called the holographic display.
Holographic displays are most often called images that are non-melic. In "Star Wars" you see some holograms of a person who are moving somewhere in space. But there is no holography real. No holography when they make any consoles for photographs for shooting. Holography is when the three-dimensional image is displayed in free spaceAt the same time, a two-dimensional medium remains as a medium of information, that is, a regular film, a digital information carrier, multiple image recording, and then synthesis into a three-dimensional image.
How is the holographic display? First of all, we need a source of light with very good quality - three lasers. So that a person has a complete color representation, he needs three RGB lasers. The next required element is the lighting system to convert the light source from the laser to the desired format and further highlight the modulator. And as modulators now, several elements can be used for a holographic display. There is LCOS - this is a technology. Liquid Crystal On Silicon. This is the development of liquid crystal displays, but in the application to microelectronics, because everything is done on the basis of a silicon substrate: the display integrates there, it turns out to be effective and highly dependent, and this display can be used.
And the next element needs an optics that could convert this rather small image and design it into the desired format. And optics can also be holographic. But what will be characteristic of such optics? Each laser will interact with its optical element, with its part of the optical system, because selectivity in the length of the wave is very important in holography. If we do something non-selective, we immediately on any optical element formed a rainbow and a lot of interfering images.
Of course, sometimes they are used. Rainbow Holography, that is, stickers - on the same coordinate of the rainbow, and on the other visible the bulk picture. But they have limited functionality. Consequently, to overcome this, we need optical elements that interact only with their laser. For example, a holographic lens for red light will interact only with red radiation. Similarly for other lenses. Holographic screens are the same lenses that agree to the beams, which should get to the viewer, with beams forming on this microscopile.
And then a very important thing: the higher the quality of the information displayed, the more highly adding displays need to be used for holography. And moreover, the resolution of the display with ahead comes with respect to what we see. Holography generally has such a property: to reflect some information the number of pixels and samples that need to be encoded in the source of information must be twice as much. That is, the permission of microdispoles is more, with something permit, which we see in the holographic image. And this is the basic thing. That is, the hookah should have redundancy, great resolution, which we want to see in the image. And there are technological difficulties.
Where it is impossible to make one display at the same time both highly dependent, and the desired size, optics come up with schemes with an image multiplocation, where each part of the image is displayed on its microscopiles. The optical system converts separate images to one synthesized. And a person can move around this already holographic image and see it will be quite good. But in order for this system to be a working, the high-tech of all elements is needed so that they can integrate them into a small volume, because they can potentially be planned at all, that is, they can shrink with the planar microelectronics technology.
On the other hand, all optical elements that create for holography are made on flat substrates. It is very important because the entire element base of modern optics is designed for the fact that you have some kind of optical bulk element. It is volumetric, and it must be polished, very accurately produce an enlightening or, on the contrary, reflecting the coating for this item. And for holography, all possible elements are made approximately in one way - the holographic method. Each time we record some item, we modify the recording scheme. That is, we make some specialized settings on our devices to record a specific image or a particular wave front. It takes for a while, but the development of robotics allows you to hope that all this will be automated, and the transition process from one entry to another is simplified.
When evolved general Direction "Holographic display", it gave birth to very interesting applications of displays, which showed that you can make applied, simpler things, very necessary, such as displaying information for pilots or drivers on the backshield background. The key element in these display systems is a combining device for an external source of information and for local. In English it is called beam combined.When you combine the image of the world around you with a local source of information. And as a combining element, the hologram was very useful, as it is transparent.
Unlike optical elements, lenses or mirrors, the entire wave front, the entire light converts into the volume of glass or on the mirror, and the hologram can divide it. It converts part, and the part turns out to be unused. This is the so-called nonphracted light. This property holograms turned out to be key to creating HMD ( head-Mounted Display) - Displays that are attached on the head. Also for pilots and motorists there head-Up Display, that is, the display that is right in front of you. They are very comfortable, because they allow not to be distracted by the environment around you, in order to, for example, consider some kind of service information from the device.
This new area has delivered holographic optical elements on a very important position. This is a key element for HMD, because all other elements are inferior to the hologram by the scope of the imperceptibility of the display itself.
The second use of holographic optical elements is the construction of a volumetric image with a removal. What it is? This is a hologram from which the image opens. That is, it is not behind the screen, but right in front of you from the hologram the image comes out, and for part of the displays it is just necessary. For example, for physicians, when they disassemble some surgical operation, where they need to know what happened in the volume. And if you have a hologram behind the glass, then it is very difficult to get there. And to build an image in front of the hologram. And it is very useful because in this way we can feedback Somehow introduce. And for part of professions, feedback is very important, because it is like tactile sensitivity.
And in all these cases Holography helps. First, it helps, because it makes holographic screens - they are unobthewable and do not interfere. And secondly, part of the optical processing of information that is done for such displays is also holography, only a digital hologram. Full emulation of the propagation of light and its interaction with the registering medium, between themselves as interferes - all this is emulated in in electronic format in computer. And the result of this count can be displayed as a digital hologram on the media of the information and display. At this display stage, holographic and optical elements are also very important.
For full use The qualities of three-dimensional images are better to illuminate the laser for which specific illuminators are needed. And for any mobile devices, these illuminators should be as compact as possible. And then the holography also says: "Here we can." And researchers in their works show that holographic illuminators are much more compact than ordinary, traditional illuminators, lenzov or mirror. They are flat and fairly effective. And they open the way for the laser to our world, directly displaying information, because all that we are mostly visible now are LEDs or stereo systems where traditional light sources are used. And for holographic displays, the laser is a fundamental thing. It allows you to reveal most advantages of optical processing of three-dimensional information.
We go to one task from different sides - creating a holographic display for mass application. And if you watch advanced conferences, then holographic displays are already a separate section. And many decisions and works demonstrate that success is about to lead to a breakthrough.
I would like to finish with optimism, because now holography is a place where you can apply your creative forces. This is science: there are their laws, achievements, prejudice. But the area develops very quickly, and it is open, especially for young. And I hope that holography in all variety (digital, holography for integral optics, holography for displays) - this will all be very quickly developed, because basic elements has already. It is only necessary to make them creatively and get new quality.
Holographic screen- It is a fully transparent segment of the plexiglas, which is applied by the reverse projection film an invisible human eye. The projected translucent picture creates the illusion of the hologram, since the viewer sees a certain facility soaring in the air. Focusing your gaze in the image we see a clear, contrast image, while relaxing focus, we can watch through the picture.
Wide application transparent screen I received at exhibitions and presentations, since this decision is an innovative way to demonstrate information. In addition, there is a possibility of an interactive. The sensor installation allows you to reproduce content in two modes - static and dynamic. Content in statics is broadcast constantly as soon as the sensor notices changes in the environment, i.e. Either a person passes by the Goloker, or comes straight to him. At this moment, another content begins to play, usually containing more detailed information about anything. The next interactive feature is Kinect. This system It transmits not only the traffic signal, but also the volume, as a result of which can be gestures to change graphics, if this is a presentation, then scroll through the slides. Also, as an interactive option, we offer to make your holographic screen touch. This is possible due to a special sensory film, superimposed on the front of the screen. IN this case The screen turns into a large transparent tablet that is suitable not only to broadcast videos, view photos, but also to work with applications, collecting contact data, feedback.

The German company SAX3D was formed in 1998. Development Center is located in Kemnice. In the manufacture of holographic optical elements, SAX3D uses a patented system selective refraction of light fluxThat allows you to ignore any light in the room, except for the beam of the projector. This technology was based on the development of SAX3D holographic screens.
Screens SAX3D. excellent alternative The usual display means carrying an advertising or informational function. The technology of manufacturing these screens was developed several years ago by German engineers from Sax3D GmbH with the only purpose attract the attention of the audience And the screens have already found wide use in Europe in Europe.
Sax3D transparent screens based on holographic film
Technically SAX3D is a projection screen that almost completely transparent (Its base is made of durable glass) and at the same time displays a bright and contrast image created on it by a regular projector. The screen itself, thanks to which the viewers do not notice him and the main intrigue is created: how the image occurs, because there are no wires to the screen!
Content for the screen can be a regular video or a selection of photos running on a computer connected to the projector. At the same time, the only wish to the displayed materials is the location of them on a black background, which will additionally emphasize the transparency of the screen.
Currently no big office shopping center Or the event does not work out without plasma panels or LCD monitors. They have become so common and inalienable element that can be surprised by their absence rather than the presence. In this regard, many companies are looking for new funds to attract customers and technological equipment.
Glass holographic screens have become an ideal solution for such tasks. Transparent screens can be suspended to the ceiling, fixed in the floor or fixed directly on the glass of the storefronts of the store (the thickness of the projection film is only a few millimeters).
The translucent picture attracts the look, and the screen itself does not violate the space, as it allows you to look through the image. Holographic screens allow you to prengear a special charm, create a unique image and attract the attention of potential customers.
Benefits of projection holographic SAX3D screens
The image is projected by transparent holographic filmwhich is applied to the surface of the screen. In addition, the film can be applied to almost any transparent surface - for example, on the showcase.
The film size implies seamless application to screens up to 60.
The image is projected at an angle of 20, 38 or 55 degrees, which allows you to hide the projector from the eye of the observer on the basis of the room features.
In contrast to standard projection solutions that require dimming, when using screens Sax3d.the force of external lighting practically does not affect the image quality. This is possible due to the fact that the holographic film passes only the light of the beam of the projector, ignoring other light fluxes entering other angles.
Holographic screen can be used as interactive panel. This is achieved due to the additional sensor layer.
Line of holographic screens
Sax3d holographic screens can be represented as standard pseudo-coolant and in the form of holographic touch display. Each of the solutions has its technical features and is intended for various targets. The manufacturer highlights three main SAX3D screens groups:

Optical projector mounting schemes for SAX3D screens
Optical circuits are necessary for the correct positioning of the projector relative to the screen, which is critical when creating installation on the SAX3D screen. The internal structure of the SAX3D screen canvase is designed for refraction and dispersion of the light stream directed from a strictly defined angle.
The placement of the screen and the projector in accordance with the optical scheme ensures that the audience will see the maximum quality image.
We are already accustomed to plasma panels and LCD screens in everyday life. No one surprises such a display technology that appeared in recent years as 3D. The technology of creating a stereoscopic image using special 3D glasses successfully occupied its niche and is actively developing. Many experts believe that the further development of the display technology, and more precisely the real revolution in this segment will occur with the release of holographic screens. After all, in fact, modern 3D television is an intermediate step on the way of creating a real surround image, since such screens look three-dimensional only at a certain position of the head. Holographic displays in this regard can be viewed as a further development of 3D technology.
The main principle of the 3D technology used in modern TVs or cinemas is to deceive the person's eyes and make him perceive the picture of three-dimensional due to the presentation of each eye a little different pictures. This optical focus is used everywhere in the current 3D solutions. For example, the illusion of the volume and depth of the picture is created using polarization points filtering part of the image for the right and left eye.
But this technology has a significant disadvantage - the surround picture is visible to the viewer only under a strictly defined angle. Today, homemade 3D TVs without glasses have already appeared on the mass. But when viewing such a TV, the viewer must be accurately opposite the screen. It is enough to shift a little right or to the left relative to the center of the screen, and the surround picture is already starting to disappear. This lack of modern 3D screens in the near future will have to solve the so-called holographic displays.
We all remember the scenes from the famous Hollywood film like "Star Wars", where the surround appears in the form of holograms and literally hanging in the air. The hologram, in principle, is a special type of three-dimensional projected image, which can be created using laser light or other sources. It is believed that in the near future, this technology will step into our daily life. True, until the release of holographic TVs is still very far away. From time to time, interesting prototypes of devices with pseudo - holographic or advanced stereoscopic displays appear, which are of great interest among the public. But full-fledged holographic screens in affordable sale not yet.
For example, a wide application today has already found so-called pseudo holographic screens based on the use of a special translucent film or grid. Such panels simply hang to the ceiling, or fixed on the glass of the trading showcase. With special lighting, the translucent panel becomes invisible to humans. And if the image is projected on it, then it creates the impression of the pictures reigning in the air - the very hologram. The image is projected on the translucent panel using the projector. The panel allows the viewer to look through the picture. Such pseudo holographic displays have a whole number of advantages over plasma or LCD screens due to their originality, a juicy image with almost any illumination conditions and accommodation available at any point.
The projector itself, which processes the image, can remain out of sight of the viewer. The undoubted advantages of such solutions should also be attributed to good viewing angles (close to 180 degrees), high contrast of the picture and the ability to create large-size holographic screens or a certain geometric shape. Naturally, the displays on the translucent film are used, first of all, to give the premises of a specific charm and unusual effect, design of commercial spaces and television studios. Solutions with transparent panels are developed by many companies and, first of all, they are used for marketing and advertising purposes to impress consumers.
East. VisionOptics.de. In particular, SAX3D based screens based on the film. This German company applies a system of selective refraction of light, which makes it possible to ignore any light in the room, except for the beam of the projector. The basic screen is durable glass, completely transparent. It is on it that a special film is applied, due to which the screen turns into a kind of hologram and displays a contrast image projected by the projector. You can watch on such a pseudo holographic screen videos, and digital pictures. Approximately the same principle work Transscreen screens based on the use of a polyester film with special layers capable of delaying the light running from the projector.
But, of course, we are primarily interested in solutions that can be used in TVs, tablet computers and smartphones. And it should be noted that in recent years more and more interesting devices appear in this area, although most of them actually use all the same notorious 3D effect, only a somewhat supplemented and improved.
At the CES 2011 exhibition, Innovision Labs has demonstrated the public a prototype of the TV TV - TV with a holographic screen. Development was called Hoload Diamond. It is a prism capable of refracting the light coming from several projectors, which creates a full-fledged hologram, which the viewer can be considered at any angle. Moreover, journalists and ordinary visitors to the exhibition were convinced that the hologram created by Holad Diamond looks better in comparison with the volumetric pictures on 3D devices. The pictures on the holographic screen are distinguished by depth and saturated colors.
This projector-TV can be played in the hologram not only photos and pictures, but also videos, however, so far only in FLV format. At once, two models of televisions based on the same principle were demonstrated at the exhibition. The first supports a resolution of 1280 x 1024 points and weighs a 95 kilogram, and the second TV is more compact, but has permission only 640 x 480 points. The devices are quite cumbersome, but it is convenient to use them. The older version of the holographic screen can be purchased for ten thousand dollars.
Researchers from the Californian HP laboratory in Palo Alto tried to solve the eternal problem of 3D screens in their own way. To reproduce a surround picture, which would be visible regardless of the viewing angle, the researchers offered to demonstrate the image of items from different sides, simultaneously sending their picture for each eye. This is usually achieved this by using a whole system with rotating mirrors and laser devices. But California scientists took the components of the standard LCD panel, put on the inner glass of the screen in a special way a huge number of round grooves. As a result, the light is refracted in such a way that allows the viewer to see the three-dimensional hologram. In any case, the HP screen created by the HP explorers makes it possible to see a static three-dimensional image from two hundred different points, but a dynamic 3D image - from sixty-four. True, the scientists themselves note that before creating a full-fledged moving hologram, which we see into the movies, are still far away.
An interesting solution offers Microsoft Research, which has developed the Vermeer display. This screen creates a holographic picture, "steaming" right in the air in the spirit of the legendary "Star Wars". It uses the effect of an optical illusion called "Mirascript". Constructively, Vermeer consists of two parabolic mirrors and a projector with a special optical system that can reproduce up to three thousand pictures per second. The projector projects a hologram from a hundred ninety-two-points at a frequency of 15 frames per second.
The most important thing is that the overview of the three-dimensional image is available from any angle (360 degrees). Moreover, the user can successfully interact with this kind of hologram, since access to it does not block any glass panel. That is, it can react to touch. To do this, the device provides for the presence of infrared illumination and the camera, the main purpose of which is to track the movements of the man's hands.
The Vermeer display has not yet been launched into commercial production, however, it is obvious that he really has serious perspectives, for example, in the gaming industry. This innovative device appeared in 2011, and a year later apple company Posted its own display, which in many respects resembles the same Vermeer. This is an interactive screen that can display three-dimensional holograms and provide the user to interact with them.
It uses the same pair of parabolic mirrors. But there is also a difference. To project a three-dimensional picture, Apple engineers offer not a real object, but a substance possessing a photorefractive effect. Fitting on it infrared radiation Enters the visible spectrum, forming a primary three-dimensional image. The device created by Apple engineers supports gesture management thanks to the built-in sensor system.
And this year the long-awaited event was held - the world's first smartphone with holographic display. In any case, its manufacturer declares about it. Telephone Takee was developed by the Shenzhen Estar Technology Shenzhen Estar Research Company. But the development is actually very similar to the model Amazon Fire Phone released earlier and offered the ability to adapt the picture on the screen depending on the angle of view of the user. However, according to the manufacturer's assurances, in their smartphone they went a little further. Here are used sensors to track the position of the eye, located above the screen. The stereoscopic picture is created using the projection of external sensors directly on the retina of the viewer's eye, while the latter can reject its view from the screen and still see the three-dimensional image.
Thus, the Takee smartphone screen allows not only to see the three-dimensional image, but also consider it from different angles. In fairness it should be noted that Chinese development is only the usual 3D technology, supplemented by eye position tracking sensors. The display supports the resolution of 1920 x 1080 points. In addition to the screen, an innovative smartphone has the following characteristics - MediaTek 6592T processor, two gigabytes random access memory and 13 megapixel sony camera Exmor RS. Works device running Android OS. There are already available multiple applications to a smartphone that allows you to play 3D games.
Obviously, that long-awaited moment is approaching when we can see TVs, tablets and monitors that create a full-fledged holographic picture. In addition, in the near future, holographic screens technology can be used in navigation, business industry and education systems. Also, holographic images simply will not be able to pass by the area of \u200b\u200bgaming entertainment, ensuring the creation of bulk, virtual worlds with an unusually realistic picture.
