As technology evolves, we are able to discover new and different types of programming, software, hardware and systems. Among these innovations, hologram technology continues to rise rapidly.
What is Hologram Technology?
Holography, or hologram technology, is a photographic technique that records and reflects the scattered light from objects and presents them in 3D.
Among the holograms that have appeared in different ways over the years are transmission holograms and rainbow holograms which are used when it is desired to provide security such as credit cards.
The development of hologram technology was made possible by the innovative laser program, which was created in 1962 by Yuri Denisyuk of the Soviet Union and Emmett Leith of the United States and Juris Upatnieks at the University of Michigan. In the program recorded on silver halogen salt with photographic emulsion, this technology, which was later developed over time, became visible in today’s holograms, although the results were far from satisfactory.
What Holograms Do in Real Life?
Holograms appear on many items we use every day. Most ID cards and almost every credit card uses hologram technology. Holograms can be found on the CD, DVD and Bluray boxes, packages of software products, or almost any copyrighted product.
On the other hand, these security holograms, although useful for preventing duplication and fraud, are not very impressive examples. Because all these holograms do is change the shape and color as the perspective changes.
Large-scale holograms, that is to say, are examples of unusual holograms, which are created by lasers or illuminated by carefully placed lighting in a dark room. These are basically two-dimensional surfaces that can show the dimensions of 3D objects in a very realistic way. Moreover, to experience this kind of hologram, you don’t need to wear special glasses as you would in 3D cinemas.
Holograms have many amazing features. For example, one of them, even a small part of the hologram, contains the entire image disclosed.
Understanding the principles behind holograms will help you understand how holograms, your brain, and light waves work together to create a 3D image.
How do holograms work?
To make a hologram, you must first record an object or person with a laser beam in a calm and simple environment, then send this information to the recording medium and clear the image.
The laser beams are divided into two and re-directed by reflecting from the mirrors. One of the rays is directed to the object. Some of the light reflects the object and is stored on the recording medium.
The second beam (also known as the reference beam) is directed directly to the recording medium. This ensures a clear image in the region where the hologram will be formed.
These two laser beams intersect and merge with each other. The region they intersect is displayed on the recording medium and a 3D image is created.
What are 3D Holograms?
3-dimensional holograms began to take place in our lives. The 3-dimensional holograms are objects that are placed on a platform, either in the air or in the air, giving the impression that they are standing there, even though they are not actually there. This type of augmented reality has continued to evolve to date.
Microsoft’s self-developed HoloLens eyeglasses, Apple’s ARKit developed by Google and holographic products such as ARCore is available today. Hologram technology has managed to gain a place in the market and IT giant companies are racing to dominate this augmented reality world.
3D hologram imaging appears to be the next step for many digital content people use. The use of this new technology is almost endless.
The hologram projected into a room can make a 3D car concept look like it really is there. 3D presentations at meetings or conferences will impress the guests. In addition, and perhaps one of the most impressive holographic uses, holographic communication allows you to project your image in 3-D and communicate with people in a room miles away.
Holograms have the potential to significantly improve training, design and visualization opportunities in many business areas. The possibility of looking at the products in the design stage in 3D, zooming in on the details and acting on them will carry this process visibly forward.
Marketing units also develop experimental sales tactics by influencing customers through interactions with holograms and 3D holograms.
The product, which is called DeepFrame and is currently under development, may allow holographic technologies such as 3-D search that may be considered science fiction. Even though this product, which costs an exorbitant price, currently costs about $ 50,000, the competition will inevitably begin and prices will fall as the experimental studies are completed and 3D searches become widespread.
In addition, HoloPlayer (the computer-connected version has a $ 750 price tag and $ 3000 without a connection) is produced by Looking Glass Factory.
HoloPlayer can show 3D holograms on the glass layer and you don’t need special glasses or equipment to see these holograms. Mike Elgan says that you can control the 3D holograms created by this device with your gestures. Elgan said, “When you look from the opposite side, you see the front part of the image. When you change the angle you see, you can see the sides of the object. These images can be controlled by hand movements and you can reach out and hold, and rotate the 3D objects by rotating. The panning action in space also brings the image of the next object in front of you as you are familiar with. ”
With the hologram, it can also be used for the windshields of vehicles that give life to objects. The first example that will come to mind for this is the Navion developed by WayRay, which has been shown at CES.
The reflector in the dashboard reflects the navigation interface and the step-by-step navigation information on the road. Navion also warns you of the dangers or pedestrians on the way. Navion can also be controlled by gestures or voice commands.
Technology enthusiasts are looking forward to the smartphone for the 3-dimensional hologram for Samsung and LG companies have been working for a long time. On the other hand, these two companies, despite all the efforts to offer 3-dimensional hologram technology is still too early for the introduction of smart phones in our lives.
