What is Hologram technology?
In layman’s terms, hologram or holographic technology records the light that is scattered from an object. It then projects scattered lights and a 3D object. Holography technology is considered the next level of photographic technique.
Since the idea of technology was first introduced in the year 1893 by Jules Verne, it has evolved and made progress. The latest technology is the introduction of 3D holograms that allows realistic animations or objects to float in mid-air or stand on a surface. Since it is 3D, it is visible from all sides which makes it possible for a user to walk around the display.
Lately, scientists have worked hard to re-invent holograms using lasers, motion sensors, and digital processors to create holograms. The promise of real holograms becoming reality very soon is something enthusiasts await excitedly. This will radically change how we interact with and consume media.
Listed Are Some Of The Best Technologies In The World Of Holography
1 Fan Type Holograms:
This technology in its basic form is something you might have seen during special events or theme parks. Using small propellers and high-tech RGB lights, they work by switching colors in milliseconds. Speed is key and at the right speed, they are used to create a 3D effect image and project it.
The Hypervsn Wall is a new emerging device in this field that is the next level of this technology. It creates High-Definition images that are over 3 meters tall and makes it look like it is floating in thin air. The most astounding thing about this is that it uses just 65 watts of power to work its magic.
2. Digital Holographic Tabletop:
While movies are still leaps and bounds ahead of real life, there has been headway made in this field. Lately, a team based in South Korea has taken an important step in hastening the growth in this segment. They have successfully created the world’s first hologram which can be viewed in 360 degrees simultaneously. This is made possible using a series of high-powered, multi-colored, and high-speed rotating mirrors with a display built into a tabletop.
3. 3D Volumetric Technology:
This is one of the coolest in the current use of Hologram Technology. Over half a billion points of light are projected into a volumetric space every second using a highly-optimized volume rendering machine and an ultra-high-speed digital light engine.
The image using hundreds of digital cross-sections is projected onto a specially designed high-speed screen. The lights are diffused and they form a physical cross-sectional image at the right place in physical space as the photons of light hit the screen. Our eyes are then tricked into blending the layers into a single 3D image without the need for special glasses.
4. Fairy Lights:
Researchers at the Digital Nature group create 3-dimensional holograms which are interactive. They comprise tiny points of light plasma called voxels. This is made possible by using femtosecond lasers that create 3D images. The resolutions are at a jaw-dropping 200,000 dots per second. The plasma bursts are so fast that touching them will not burn you. The most exciting part is that these holograms can be felt.
5. No-logram:
This technology has been around for many years and is used by magicians and moviemakers quite extensively. It requires tracking the motion of the viewer and therefore there is no need for a headset or screen
6. Light Field Display Holograms:
Usually seen in children’s museums in the recent past, they have leaped in the right direction lately. Earlier correct angle was required to project the illusion of a 3D image using a round mirror.
Researchers now use the LCD screen to create HoloPlayer one-type machines that are capable of sending 32 views of a scene in targeted directions at the same time. Using a depth-sensing camera, allows users to interact with the hologram-like object in real life or as a touchscreen app.
7. Pepper’s Ghost:
If you are aware of the use of hologram technology, this is one of the most familiar holograms, especially if you are a music enthusiast. Revamped designs in old technology have made it an awesome hologram. MDH hologram was the pioneer company that mastered flexible and realistic hologram technologies which are used extensively for performance venues all over the world.
‘What is hologram technology?‘ can be answered in simple terms as a progressive step into the future of viewing images or videos. An insurmountable dream till fairly recently, it has become a reality thanks to the hard work of researchers, scientists, and hologram enthusiasts all over the world. If you also want to interact with this matchless technology, instantly get in touch with Vision 3D for acquiring ample products including a 3D holographic screen, table, wall, room, and arcade games.
If you have seen holograms of artists such as Michael Jackson or Tupac, you are well aware that they are very realistic. This is made possible using high-end motion capture technology coupled with 3D CGI. They recreate a person and project them into an almost invisible pane of glass.
