Hologram Technology and Samples
As technology develops, we have the opportunity to explore new and different types of programming, software, hardware and systems. Hologram technology, which is among such innovations, continues to rise rapidly.
What is Hologram Technology?
Holography, that is, work or production on hologram technology, is a photographic technique that records the reflected and scattered light from objects and presents them in 3D.
Among the holograms that have appeared in different forms over the years, there are the rainbow holograms, which are transfer holograms and are used when security is desired, such as credit cards, with a variety that allows the light to pass through and the image to appear on the side.
The development of hologram technology was made possible by the innovative laser program that enables recording objects in 3 dimensions, which was created by Yuri Denisyuk from the Soviet Union and Emmett Leith and Juris Upatnieks from the United States in 1962 at the University of Michigan. Although the results of the photographic emulsion recording program on silver halogen salt were far from satisfactory, this technology developed over time became visible in today's holograms.
What Do Holograms Do in Real Life?
Holograms appear on many items we use every day. Hologram technology is used in many ID cards and almost every credit card. Apart from these, holograms are also found on CD, DVD and Bluray boxes, packages of software products, that is, on the packaging of almost every copyrighted product.
On the other hand, although the security holograms mentioned are useful for preventing copying and fraud, they are not very impressive examples. Because all such holograms do is change shape and color as the perspective changes.
Large-scale holograms, that is, the types created with lasers or brought to life by carefully placed lighting in a dark room can be shown as extraordinary hologram examples. These are basically two-dimensional surfaces that can show the dimensions of 3-dimensional objects in a fairly realistic way. Moreover, in order to experience this kind of hologram, you do not need to wear special glasses as you should in 3D cinemas.
Holograms have many surprising properties. For example, one of them, even a small part of the hologram, contains the entire image rendered.
Understanding the principles behind holograms will help you understand how holograms, your brain, and light waves work together to create a 3-D image.
How Do Holograms Work?
In order to make a hologram, you must first record an object or a person in a calm and plain environment with laser beams, then send this information to the recording medium and clear the image by clearing it.
Laser beams are divided into two and reflected from mirrors and redirected. One of the rays is directed at the object. Some of the light reflects the object and is stored in the recording medium.
The second beam (aka the reference beam) is directed directly into the recording medium. This ensures that the rays form a clear image in the area where the hologram will be formed.
These two laser beams intersect and merge with each other. The region where they intersect is displayed on the recording medium and a 3-dimensional image is created.
What Are 3 Dimensional Holograms?
3D holograms have started to take place in our lives. 3D holograms are objects that are either floating or positioned on a platform that give the impression of standing there, even if they are not actually there. This type of augmented reality has continued to develop steadily to this day.
Products such as HoloLens glasses developed by Microsoft, Apple's ARKit and ARCore developed by Google and presented with holograms are available today. Hologram technology has managed to gain a foothold in the market, and IT giant companies are racing to dominate this world of augmented reality.
3D hologram imaging seems to be the next step for a lot of digital content people use. The uses of this new technology are almost endless.
The hologram projected into a room can make a 3D car concept appear as if it was really there. 3D presentations at meetings or conferences will impress the guests. In addition to all of these, and perhaps one of the most impressive hologram uses, holographic communication allows you to project your image in 3D in a room miles away and communicate with the people there.
Holograms have the potential to significantly improve training, design and visualization opportunities in many business fields. The possibility of looking at the products in the design phase in 3D, zooming in on the details and making changes on them will visibly move this process forward.
Marketing units also develop experimental sales tactics by influencing customers through interactions with holograms and 3D holograms.
The product, called DeepFrame and is currently under development, can enable holographic technologies such as 3D search that can be thought of as science fiction. Although this product, which costs an exorbitant price, currently costs around 50 thousand dollars, as the experimental studies are completed and the 3D searches become widespread, competition will inevitably begin and the prices will decrease.
In addition, the product named HoloPlayer produced by the developer called Looking Glass Factory (The computer-connected version has a price tag of 750 dollars, and the version that can work without the need for connection has a price tag of 3000 dollars) is currently on the market.
HoloPlayer can display 3D holograms on the glass layer and you do not need any special glasses or equipment to see these holograms. Mike Elgan states that you can control the 3D holograms created by this device with your gestures. “When you look directly across it, you see the front part of the image. When you change the angle you look at, you can see the sides of the object. These images can be controlled with hand gestures and you can reach and hold, and you can rotate 3-dimensional objects with rotation. The scrolling movement you make in the space brings you the image of the next object as you are used to. " briefly explains what the product can do with his words.
With the hologram, giving life to objects can also be used for windshields of vehicles. The first example that comes to mind for this is Navion, which was developed by WayRay firm, which was showcased at CES.
The reflector placed on the dashboard reflects the navigation interface and step-by-step navigation information to the road. Navion warns you by identifying hazards or pedestrians on the road. Navion can also be controlled by gestures or voice commands.
For smartphones, which technology enthusiasts are looking forward to, Samsung and LG companies have been working for a long time for the 3D hologram. On the other hand, these two companies think that it is too early for smartphones that can offer 3-dimensional hologram technology, despite all efforts, to enter our lives.
The Future of Hologram Technology
Although the public finds hologram technology impressive, this technology is an industry in itself. The market share for hologram technology in 2020 is predicted to be 5.5 billion dollars. Below, we have listed the areas where hologram technology is used impressively for you.
Geographical information is vital to military strategies. Maps depicted holographically with all their dimensions have the potential to improve discoveries. These 3D holographic maps allow soldiers to see the battlefields and the cover layer in the area and get better training for the mission.
The holographic page, created by collecting digital image data, draws attention with its easy folding and portability, as well as looking at and evaluating the map on it. Such maps have the potential to aid rescue efforts in natural disasters or similar situations.
Incredible amounts of data emerge every day and digital storage capacity increases every year. Hundreds of gigabytes of data, consisting of photos, videos and documents, are stored on our personal computers. Failure of the disk where this information is stored can cause enormous losses.
Although holograms create impressive images, this technology does not only record and display objects. Holograms are capable of recording pure data, even massive amounts of data. Holograms have the potential to hold unimaginable amounts of information. The current prototype can store 4.4 million pages of information on a DVD-like disc and provides long-term security.
If you make an optical hologram of information on a page and then shred it, you have the opportunity to put these pieces together at any time. Thanks to this feature, holographic data storage shows itself as very reliable. Unlike CDs and DVDs, which store data by writing on disc, holograms store data in three dimensions and these information-laden pages can be stored on top of each other.
Hologram technology is very close to revolutionizing the medical field. Thanks to this technology, patient information can be displayed for the training of medical students and surgeons.
MRI and ultrasound scans used today reveal complex data and use advanced imaging technology. Hologram technology can reveal fully colored 3D holograms created with the aid of a computer.
No device or glasses are needed to use three-dimensional images for training and viewing purposes. Students and doctors can comfortably examine 3D images. These images can be the brain, heart, lungs, liver, nerves or muscles, which are highly complex organs and systems in our body.
Fraud and Security
Holograms are complex and difficult to make, allowing them to be very useful in the field of security.
If you use a credit card, you are carrying a hologram in your pocket. The gray square on your credit card is a white luminous transfer hologram with a mirror on the back. This square, with a three-dimensional image on it, moves and changes color as you move and change its angle. Such holograms are extremely difficult to reproduce.
The holograms on the coins also provide security. The new 5 Pound banknotes printed in the UK have an image of Big Ben that changes color as they move. These banknotes also feature a 3D hologram of the queen's crown.
With the widespread use of holograms, artists began to experiment in this area. Artists from all over the world have begun to shape the space using three-dimensional holograms, create artworks from images, prepare videos of their 3D works, or create sculptures using only light.
Recently, an exhibition with creative holograms was held in London, the capital of England. In addition, art works made with holograms selected from international artists were presented to art lovers in New York, Canada, Italy, United States of America and England.
Impressive Examples of Hologram Technology Existing Today
Now, let's take a look at the applications of Hologram technology used today. Below, we have listed the top 6 examples of hologram technology that we can come across in real life.
The ones on this list are just as crazy as science fiction novels, and they are all available today.
Ever since Jules Verne dreamed of hologram technology in 1983, users as well as technology and entertainment companies have been dreaming of this innovation. Since we witnessed the hologram of Princess Leia, one of the characters in the Star Wars series about 40 years ago, interest in this technology has increased. Unfortunately, for many years, this kind of development was limited to the science fiction world. Because it seemed impossible to create a 3-dimensional image.
Nowadays, we can say that we are finally getting closer to our dreams about hologram technology. Scientists around the world continue to develop new ways of using lasers, modern digital processors and motion sensors. Thanks to these developments and advances, it seems that our daily use of technology, media and social media will undergo a radical change in the near future.
Some of the hologram technologies that these developments have already introduced into our lives are listed below for you:
1- Aerial Burton Laser Plasma Holograph
Until recently, all examples of holograms needed a helper, such as glass, smoke or water, to which light could reflect. But this is no longer the case. The firm called Aerial Burton can create 3-dimensional images in the space using plasma laser thanks to the holographic reflector it designed and developed. This study, which can still be considered as primitive, reveals that despite all its deficiencies, light can be seen without the need for a reflective surface. The technology that makes 1 kW infrared laser pulses focuses its shots to a specific point in the air through a 3D scanner and creates plasma by ionizing the molecules in the air. Although technology still needs a lot of work and development, it stands out as a big step towards the introduction of holographic images that exist in the vacuum from nothing into our lives.
2- Pepper's Ghost
If you live with the world of music, this hologram will probably look familiar to you. This hologram, which is an old technology illusion, has been made impressive with new designs. MD Hologram firm, known for its technology that they prefer to call “Returning to Digital Life”, is also closely related to performing arts as it is a leading company in realistic photographic and animated holograms. The realism of their work can be understood from the holograms they made for Tupac, Michael Jackson and Indian Prime Minister Narendra Modi. Combining advanced motion capture technology with fully 3D CGI, the company is able to recreate a person from head to toe and project them onto a barely noticeable glass.
3- Propeller Type Holograms
You may have encountered primitive versions of the technology we mentioned at theme parks or special events. These holograms, which are brought to life by bringing together small propellers and high-tech RGB (R: Red - Red, G: Green - Green, B: Black - Black) lighting, can change color in milliseconds. When turned at the right speed, images can be brought to life by creating a 3D effect with this technology. Thanks to a recently developed device called Hypervsn Wall, the technology we mentioned is taken one step further, and images larger than 3 meters can appear in space with completely high resolution. All this is done using only 65 watts of energy.
4- Light Field Holograms
This type of holograms, which were used in museums for children in the past, developed more and more day by day. In the past, images created by creating 3D illusion with curved mirrors could only be seen when viewed from the right angle. Now, using LCD screen technology, scientists can develop machines such as HoloPlayer One and project the 32-angle view of the image to be produced in the desired direction at the same time. The "light field" created in this way allows a scene to be created in real dimensions. With this hologram technology, which is possible to work together with depth sensing sensors, users can interact and use the hologram as in reality or touch screens.
5- Digital Holographic Desktop
Obviously, the holographic table used by the Tony Stark character we know from "Iron Man" and "Avengers" movies is not a technology we can have yet, given the technology we have. But a team from South Korea has managed to take an important step that could bring us closer to this technology. The team was able to create the world's first holographic imager with a 360-degree viewing angle, using a series of multicolor, high-energy lasers and high-speed rotating mirrors. The team also took a big step by placing this success on your table.
6- Tabletop Holograms
In this example, we see a hologram table called Hololamp, which can perform its task without the need for glass. The device, which allows you to control it manually by projecting a flat surface, gets help from motion detector and scanner cameras for this. Although this product called Hololamp is not as cool as the other hologram technologies we mentioned, it makes up for this deficiency with ease of use.
Holograms used to be the subject of only science fiction movies. But the development and use of this technology has overshadowed science fiction and has become a part of our daily lives.
While we only use a small part of the benefits of hologram technology today, it seems like holograms will have a much bigger place in our lives in the future, thanks to the ongoing work of inventors and developers.
As a result, although there is still a lot of work to be done in the field of hologram technology, science constantly improves itself and continues to progress for you.
