All of you remember Princess Leia, appearing as a floating image in the first episodes of Star Wars at some time in the 1980s, a broader audience was presented with the word "hologram." For years, it seemedhologramsIt would be limited to science fiction singing forever.However, recently, things began to change thanks to advances in optical technology. In real life, holograms are three -dimensional virtual images created by the interference of light beams that reflect real physical objects.Holograms retain depth, paralax and other properties of the original element.They are excellent for presenting complex technical concepts and visually showing visually attractive products. So what is a hologram?In a nutshell, holograms are three -dimensional images generated by interferential light beams that reflect real physical objects.Contrary to conventional 3D projections, holograms can be seen with the naked eye.What is hologram technology?
There are two ways to create holograms: through the computer, with augmented reality glasses and physical views, for optical views.Two types of holograms: stereotyped and realistic.
Stereotyped holograms
The most common and recognizable example of a stereotyped hologram is Microsoft Hololens.In 2015, Microsoft became the first company to present the Hololens holographic glasses.The technology that technology has revealed is widely used today to createaugmented reality.
To create holograms for Hololens, content creators use Holostudio software.Users can import models of other services or create 3D objects with the help of the application.Sometimes these objects overlap the images of the surrounding world by using virtual reality glasses.
The result is an image that looks very similar to Pokemon Go.The only difference is that in Hololens, instead of seeing fantastic dinosaurs, it is implementing a virtual work space, an educational office or a virtual conference with colleagues.
Hololens makes it possible by linking aerial objects with traditional computer programs for work and entertainment.Brief demonstrationFor more information aboutHolographic technology.
Realistic holograms
EM 1947, Dennis Gabor-A Hungarian-British physicist-He developed today's modern holograms theory while working in an electronic microscope.However, optical holography did not advance to the advent of the laser in 1960. A laser emits a powerful explosion of light that lasts only a few nanoseconds.
This makes it possible to obtain holograms of high -speed events, such as an arrow or a bullet in flight.The first human place based on laser was created in 1967, which raided the way for many other applications ofHolographic technology.
So,How do holograms work?Holography is a unique method of photography, through which 3D objects are recorded using a laser and are then restored with the greatest possible precision to correspond to the object originally recorded.When they light up through a laser, holograms are able to form an exact 3D clone of the object and double their resources.
To produce a precise vision of a hologram at a certain point in space, two waves of light should be coordinated in motion: a reference wave and an object wave.Babies are formed by separating the laser beam.
The reference wave is created directly by the light source and the object wave is reflected in the registered object.There is also a photographic plaque in which the dark stripes are "printed", depending on the distribution of electromagnetic energy (interference) in a certain location.
A similar process occurs in the common photographic film.However, to reproduce an image, an impression on photographic paper is required.However, during the active use of holograms technology, everything happens slightly differently.
To reproduce a "portrait", the photographic plate must be "illuminated" with another wave of light near the reference wave, which turns the two waves into a new wave of light that runs next to the object wave.Almost totally precise reflex of the object itself.For a better understanding ofHow holograms occur, look at this shortvideo.
What are some of the most common cases for the use of the industry?
Holographic technologyIt is used in many ways in several sectors.The list below includes some of the most popular examples:
1. Telecommunications
In 2017, Verizon (USA) and South Korea Korea (South Korea) made the first holographic call using 5G technology.To enable the call, two holograms were formed.They formed a completely capable enclosure of transmitting the emotions and gestures of the user.
2. Education
In 2015, the winner of the Nobel Prize and Professor of Physics at Stanford University, Karl Wieman, spoke at Nanyang University (Singapore) without leaving the United States.
In 2013, he presented the University of São Jorge de Londonhologramsable to show the work organs of a human body.The presentation presented three -meter -long images, a skull and other body parts.
3.Space navigation
In 2017, scientists from the Technological University of Munich developed a method to obtainhologramsusing a Wi-Fi router.The method described in the study allows the creation of copies of facilities that show objects around them.This technology can be used to find and rescue the victims trapped under an avalanche or collapse buildings.
4. Marketing and direct sales
Product holograms are a new marketing maneuver to attract customer service.The help of a hologram, can expand a 3D copy of a product and make it visible everywhere.This is convenient for customers who want to see the desired purchase in detail.
In 2017, Barbie presented a holographic robotic doll that responds to voice commands.The toy could answer questions about the weather and discuss other topics.
5. Music shows
A hologram of Eric Prydz's face acted as the closure of its 5.0 epic program in London, 2017. The presentation of the popular French DJ was accompanied by an impressive laser show.At the end of the night, more than 300 lasers formed a volumetric hologram of DJ's head since then, DJ's shows were always accompanied byUse of holograms to create a unique atmosphere.
6. The return of historical figures
In 2012, Digital Domain Studio, specialized in VFX forDevelop Hollywood stars in movies, I returned life to Tupac Shakur as an exceptional 3D hologram.Using an actor and double body, they created animations for a realistic Tupac digital avatar.In 2014, Tupac appeared in Coachella in its digital human form.
As in Tupac or in any other educational project, such as the creation of a virtual history museum, holograms production requires additional planning and coordination.hologramsThey are created according to the use of exclusive digital avatars for people who have left us a long time ago.
Creating 3D models, animated movements and synthesizing authentic voices is not a simple task.In the case of the latter, respect can drastically reduce the cost and time of time associated with the reproduction of an authentic voice.In other words, we cannot only bring back to the voice of Tupac of the past, but it is also possible to create a new authentic content as if the singer was still with us.Interested in learning more?How can we help.
The future of holographic technology
The future of holography is at the intersection of AI, digital human technology andVoice cloningThe constant increase in world computer power will allow the creation of digital human models that will become an always fast pace that will make them more difficult to say, beyond the real ones.
In turn, the evolution of holographic technologies will lead to growing availability and portability.Imagine if the holographic content could one day be as accessible as the transmission content: holographic cinema, holographic theater, music shows.
Augmented realityIt will no longer require the use of special glasses, but will be integrated directly into landscape objects.We know how the holographic crossings of pedestrians and holographic advertising.But we can only imagine how our cities and lives will be changed as evolutionary.The technology rhythm will continue to accelerate.
