Holograms in real life: how technology works and industries (2023)

Holograms in real life: how technology works and industries (1)

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.

What is hologram 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.

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.

(Video) How Does a Hologram Work?

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.

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.
