No Longer Science Fiction: Scientists Develop First-Ever Touchable 3D Holograms
UPNA researchers created a 3D mid-air display allowing natural hand interaction with virtual objects using an elastic diffuser and high-speed projections. Dr. Elodie Bouzbib from the Public University of Navarra (UPNA), together with Iosune Sarasate, Unai Fernández, Manuel López-Amo, Iván Fernánd
In a first, breakthrough 3D holograms can be touched, grabbed and poked
Futuristic holograms you can manipulate have become a reality sooner than we thought, thanks to breakthrough display.
Scientists Built Holograms You Can Manipulate with Your Hands. This Is How the Future Feels
You’ve probably seen a movie in which a character pulls up a hologram display that they can poke, prod, and manipulate as easily as you could mess with a real object sitting on a desk in front of you.
The idea is so ubiquitous in science fiction that it’s become nearly synonymous with the word “hologram.” In almost every news story written about hologram technology and how far it has come, at some point, a disclaimer has to be made explaining that ‘it’s not quite Tony Stark tech, but it’s still cool!’
Holograms that can be grabbed and manipulated
Researchers have succeeded, for the first time, in displaying three-dimensional graphics in mid-air that can be manipulated with the hands. The team includes Doctor Elodie Bouzbib, from Public University of Navarra (UPNA), together with Iosune Sarasate, Unai Fernández, Manuel López-Amo, Iván Fernández, Iñigo Ezcurdia and Asier Marzo (the latter two, members of the Institute of Smart Cities).
“What we see in films and call holograms are typically volumetric displays,” says Bouzbib, the first author of the work. “These are graphics that appear in mid-air and can be viewed from various angles without the need for wearing virtual reality glasses. They are called true-3D graphics.
They are particularly interesting as they allow for the ‘come-and-interact’ paradigm, meaning that the users simply approach a device and start using it.
Korean researchers develop a processor for real-time hologram generation
Korean researchers have developed a digital holography processor that converts two-dimensional (2D) videos into real-time three-dimensional (3D) holograms. This technology is expected to play a key role in the future of holography, as it enables the instantaneous transformation of ordinary 2D videos into 3D holograms.
The Electronics and Telecommunications Research Institute (ETRI) has announced the development of a programmable semiconductor-based digital holographic media processor (RHP) using Field Programmable Gate Array (FPGA) technology. This processor can convert 2D video into 3D holograms in real-time.
The real-time holography processor is the world’s first to utilize high-bandwidth memory (HBM) to generate real-time, full-color 3D holograms from 2D video. Notably, all the hardware required for hologram generation is integrated into a single system-on-chip (SoC).
Quantum Holograms Transform Light Into Unbreakable Security
Quantum entanglement, one of the strangest and most powerful aspects of physics, has just been taken to a new level with the use of metasurfaces.
Researchers have discovered a way to create quantum holograms, where entangled photons encode intricate information with unprecedented precision. By leveraging the properties of metasurfaces, they demonstrated control over entangled holographic letters, opening doors to secure quantum communication and even anti-counterfeiting technology.
Unlocking the mysteries of quantum entanglement.
Quantum holograms: Metasurfaces entangle light and information in new study
Quantum entanglement is a fundamental phenomenon in nature and one of the most intriguing aspects of quantum mechanics. It describes a correlation between two particles, such that measuring the properties of one instantly reveals those of the other, no matter how far apart they are. This unique property has been harnessed in applications such as quantum computing and quantum communication.
A common method for generating entanglement is through a nonlinear crystal, which produces photon pairs with entangled polarizations via spontaneous parametric down-conversion (SPDC): if one photon is measured to be horizontally polarized, the other will always be vertically polarized, and vice versa.
Meanwhile, metasurfaces—ultrathin optical devices—are known for their ability to encode vast amounts of information, allowing the creation of high-resolution holograms. By combining metasurfaces with nonlinear crystals, researchers can explore a promising approach to enhancing the generation and control of entangled photon states.
