10 Best Real World Applications of Hologram Technology

Holograms have been a dream of tech and entertainment companies as well as consumers ever since Jules Verne first introduced the idea of the technology back in 1893. But the popular craving for such devices really came into vogue when Princess Leia appeared as a floating image in Star Wars over forty years ago. Unfortunately, for years it looked like such things were going to be forever relegated to the realms of science fiction. The challenges of creating a 3D image in the thin air simply seemed insurmountable.

Finally, however, it looks like we are approaching the day where that dream of real holograms may actually become a reality. Scientists around the world have come up with new and inventive ways to use lasers, modern digital processors, and motion sensing technologies to create several different types of holograms which could change the way we consume and interact with media in the very near future.

Here is our list of some of the coolest holographic technologies around today. Check it out, and share it with your friends to help the technology reach the mainstream, because as Princess Leia said, “You’re my only hope.”

1. The Aerial Burton Laser Plasma Holograph:

Until recently, any «hologram» examples have required glass, smoke, or water to bounce light from, but not anymore. A company known as Aerial Burton has created a holographic projector that uses a plasma laser to float a 3D image in mid-air. At the moment it’s very rudimentary stuff but it shows that light can be viewed without the need to bounce it off a surface. The technology uses a 1kW infrared pulse laser which is focused on direct points in the air via a 3D scanner causing the molecules in the air to be ionized to create a plasma. While this tech is rudimentary right now it’s an important step in the right direction to ubiquitous holographic displays in thin air.

2. Pepper’s Ghost:

If you’re a fan of music, then this is one hologram you are probably familiar with. It’s an old technology of illusion, but new designs have made it awesome. Pioneers of something they like to call “digital resurrection,” MDH Hologram was the first company to master photorealistic and flexible hologram technology for performance venues. It can be incredibly realistic too, as proven by the holograms of Tupac, Michael Jackson, and even Indian Prime Minister Narendra Modi. Using high-end motion capture technology and full 3D CGI they completely recreate a person from head to toe, then projects them into a nearly invisible pane of glass.

3. Fan Type Holograms:

You may have seen rudimentary forms of this technology before at theme parks or special events. They work using small propellers merged with high tech RGB lights that can switch colors in milliseconds. When spun at the right speed they can be used to create an image with a 3D effect. Recently a new device known as The Hypervsn Wall has emerged which takes this technology to the next level, creating fully HD images over 3 meters tall that at least give the appearance of floating in the air, all while using a mere 65 watts of power.

4. Light Field Display Holograms:

These are the types of holograms you might have seen in children’s museums growing up, but they are becoming more advanced by the day. It used to be that a round mirror could project the illusion of a 3D image from the right angle, but now researchers are using LCD screen advancements to create machines like the HoloPlayer One, which sends 32 views of a given scene towards their designated directions simultaneously. This creates a “field of light”, which a scene that occupies the same physical volume would have given out. Paired with a depth-sensing camera allows a user to interact with the hologram just like they might with a real object or touchscreen.

5. Digital Holographic Tabletop:

Admittedly, the world of Tony Stark holographic tables is still years ahead of our current technology, but recently a team out of South Korea made an important step in that direction. They created the world’s first hologram capable of being viewed simultaneously in 360 degrees by using a series of multi-colored, high powered lasers and a high-speed rotating mirror display that could be built into, you guessed it—a tabletop.

6. Physical Holograms:

In a slight departure from the traditional idea of a hologram (but still incredibly cool in it’s own right), researchers at MIT created a tangible informed dynamic shape display called inFORM that can render the shapes of people and objects on 2D surfaces. To do this it uses up to 900 motor driven columns in a tiny area that are capable of sculpting shapes in real time. Most importantly though it looks SUPER COOL!

7. No-logram:

The technology for this type of hologram has been around for years and even used extensively by magicians and filmmakers, but it to an artist to perfect it. Joanie Lemercier uses 2D projections paired with a motion sensor to give the impression and functionality of a 3D image that is incredibly high-def and realistic feeling. And since it is tracking the motion of the viewer and not a camera, no headset or screen is required.

8. Table Holograms:

Though not true 3D holograms like the Digital Holographic Tabletop above, there are a couple other holographic table products worth mentioning as they are available right now and very cool. The Euclideon Hologram Table is an immersive, multi-user system that coordinates atoms of light with an incredible algorithm that can handle 1000GB of graphics data, creating stunning visuals. Unfortunately, it does require special lenses to use.

Then there is the Hololamp, which is the first glasses-free hologram table. It creates a projection on a flat surface that can be manipulated manually by a motion tracking scanning camera. More user-friendly, but not quite as cool looking.

9. 3D Volumetric Technology:

Possibly the coolest looking current holographic technology, Volumetric holograms like those created with the Voxon VX1 display use an ultra-high-speed digital light engine and a highly-optimized volume rendering engine to project over half a billion points of light into a volumetric space every second. Hundreds of digital cross-sections of an image are projected synchronously onto a specially designed high-speed reciprocating screen. As the photons of light hit the screen, they are diffused and form a physical cross-sectional image at precisely the right place in physical space, and our eyes are tricked into blending those layers together into 1 single, 3D image. No glasses required.

10. Fairy Light:

Don’t be fooled by its name, this is one of the most exciting developments in holographic technology ever. Researchers at the Digital Nature Group have found a way to create three-dimensional, interactive holograms comprised of tiny points of light plasma called voxels. They accomplished this using femtosecond lasers (a femtosecond is a quadrillionth of a second, and the lasers transmit bursts that last 30 to 270 femtoseconds), that can create 3D images with resolutions up to 200,000 dots per second. And since the plasma bursts are so fast, touching them won’t burn you.

Most excitingly though, these holograms are actually tangible—they can be FELT! But what exactly does a miracle of modern science—light bursting to life in brilliant images—actually feel like? Well, according to the team’s principal investigator, Yoichi Ochiai, it feels like sandpaper.

So, yeah, there’s still some work to be done. But hey, that’s science for you.

What is a Hologram?

By Robert Workman published 23 May 13

Holography is a photographic technique that records the light scattered from an object, and then presents it in a way that appears three-dimensional. Holograms pop up in movies such as «Star Wars» and «Iron Man,» but the technology has not quite caught up to movie magic — yet.

Various types of holograms have been made over the years, including transmission holograms, which allow light to be shined through them and the image to be viewed from the side; and rainbow holograms, which are used for security purposes — on credit cards and driver’s licenses, for example.

How holography works

To create a hologram, you need an object (or person) that you want to record; a laser beam to be shined upon the object and the recording medium; a recording medium with the proper materials needed to help clarify the image; and a clear environment to enable the light beams to intersect.

A laser beam is split into two identical beams and redirected by the use of mirrors. One of the split beams, the illumination beam or object beam, is directed at the object. Some of the light is reflected off the object onto the recording medium.

The second beam, known as the reference beam, is directed onto the recording medium. This way, it doesn’t conflict with any imagery that comes from the object beam, and coordinates with it to create a more precise image in the hologram location.

The two beams intersect and interfere with each other. The interference pattern is what is imprinted on the recording medium to recreate a virtual image for our eyes to see.

The recording medium, where the lights converge, can be made up of various materials. One of the most common used with hologram creation is photographic film, with an added amount of light-reactive grains. This enables the resolution to be higher for the two beams, making the image look much more realistic than using the silver halide material from the 1960s.

History of holography

The development of hologram technology started in 1962, when Yuri Denisyuk, in the Soviet Union, and Emmett Leith and Juris Upatnieks at the University of Michigan developed laser technology that recorded 3D objects. Silver halide photographic emulsions were used for the recording medium, though the clarity of said objects wasn’t perfect at the time. But new methods involving the conversion of transmission with the refractive index allowed holograms to be improved over time.

Future of holography

For now, holograms are static. Recent presentations, such as CNN’s special effect of a reporter appearing live from another location, and the late Tupac Shakur «appearing live» at a music festival, are not «true» holograms.

However, new holographic technology is being developed that projects 3D images from another location in real time. The images are also static, but they are refreshed every two seconds, creating a strobe-like effect of movement. The researchers hope to improve the technology over the next few years to bring higher resolution and faster image streaming.

And in March 2013, it was announced that a group of researchers from Hewlett Packard Laboratories has developed glasses-free, multi-perspective, 3D display technology for mobile devices.

Покупая продукт потребитель обычно обращает внимание на срок его годности, но на некоторых товарах не может найти. Это объясняется тем, что многие производители указывают информацию скрыто в форме батч кода. Как правило, такое встречается на парфюмерии и косметике. Рассказываем, как проверить желаемый парфюм по батч коду и как с его помощью проверить подлинность товара.

Проверить батч код онлайн

В сети легко найти сервисы, которые расшифровывают батч код, указанный на парфюмерии. Сайты предлагают бесплатно воспользоваться косметическим калькулятором и доступны любому пользователю. Иногда для проверки нужна регистрация, в большинстве случаев она не требуется.

Обычно платформы действуют по одинаковой схеме. Многие ресурсы функционируют по похожей схеме. Алгоритм того, как проверить на сервисе батч код нужного парфюма:

После последнего действия возможны два варианта.

Если маркировка верна, то сервис выдаст данные о туалетной воде или другом продукте (дату выпуска и срок годности). Также таким образом можно узнать о просрочке. При неверном кода информация не откроется.

Что такое батч код

На многих духах не указаны год выпуска и годность в привычном виде. При этом, есть ненормируемая комбинация из цифр и букв, которая указывается на стикере или наносится прямо на флакон методом тиснения или гравировки. Это объясняет то, что такое непривычный батч код. Некоторые примеры приведены в таблице.

Шифр позволяет проверить:

Кроме практичных целей правильно указанный батч код свидетельствует об оригинальности парфюма. Дело в том, что подобный шифр используют не все производители, но именитые и популярные фирмы не упускают такой вид маркировки.

Где находится батч код

Номер расположен на упаковке и флаконе одновременно, либо на чем-то одном. Местом, где находится код, может быть дно коробки и баночки или их боковая сторона.

Найти батч код просто, потому что изготовитель качественного продукта не скрывает информацию о нем. Крупные бренды дублируют код на двух упаковках.

Если на флаконе в торговом зале не обнаружено батч-кода, то можно обратиться к консультанту с просьбой о предоставлении сертификата качества или написать в службу поддержки необходимой компании.

Как проверить парфюм по батч коду

Еще до покупки парфюмерной продукции код нужно оценить визуально. При этом важно, чтобы:

Если последний пункт не выполнен, то однозначно это подделка.
