Researchers Have Developed an Incredible New Method of Producing Realistic Holograms

Posted by in categories: encryption, holograms

Researchers have developed a new method for creating realistic 3D holographic projections that are three orders of magnitude better than the current state-of-the-art technology. Previous attempts to improve the resolution of holograms have run into three basic roadblocks. However, this new ultrahigh-density method shows that two of those have now been solved, dramatically improving the overall quality, resolution, and appearance of holographic projections.

“Our new method overcomes two long-existing bottlenecks in current digital holographic techniques — low axial resolution and high interplane crosstalk — that prevent fine depth control of the hologram and thus limit the quality of the 3D display,” said Lei Gong, who led a research team from the University of Science and Technology of China. “Our approach could also improve holography-based optical encryption by allowing more data to be encrypted in the hologram.”

AdS/CFT Proves Its Usefulness

One of the first uses of AdS/CFT had to do with understanding black holes. Theoreticians had long been grappling with a paradox thrown up by these enigmatic cosmic objects. In the 1970s Stephen Hawking showed that black holes emit thermal radiation, in the form of particles, because of quantum mechanical effects near the event horizon. In the absence of infalling matter, this “Hawking” radiation would cause a black hole to eventually evaporate. This idea posed a problem. What happens to the information contained in the matter that formed the black hole? Is the information lost forever? Such a loss would go against the laws of quantum mechanics, which say that information cannot be destroyed.

Beam me up, Proto! NBC’s “California Live” uses patented Proto hologram tech

Posted by in categories: holograms, innovation

We showcase the Proto infinity wall, the Proto Epic, and the Proto M. Watch and enjoy, or else.

None of this happens without the entire team at Proto. The Protopians are made up of world class engineers, salespeople, resellers, investors, producers, developers, and partners. Without them, Proto is just a good idea. They’re the people who actually make these innovations happen.

Scientists Use “Acoustic Holograms” To Form Particles Into Complex 3D Shapes

Posted by in categories: biological, holograms, particle physics

That’s exactly what researchers in Germany set out to do, making use of “acoustic holograms” to form distinct 3D shapes out of particles suspended in water — all in “one shot,” said study lead author Kai Melde, a researcher from the Max Planck Institute, in a press release.

According to a study on the work, published last week in the journal Science Advances, the researchers were able to create a helix and a figure 8 out of silica gel beads, assembled biological cells into spherical clumps, and even provided a compelling concept for forming the shape of a dove in future experiments.

These acoustic holograms work by cleverly manipulating the pressure exerted by high frequency ultrasonic waves via the inexpensive use of a conventionally 3D-printed plate.

Why all of Hollywood UI looks the same

Posted by in categories: entertainment, holograms, robotics/AI, space travel, wearables

Science fiction films love to show off huge leaps in technology. The latest Avatar movie features autonomous, spider-like robots that can build a whole city within weeks. There are space ships that can carry frozen passengers lightyears away from Earth. In James Cameron’s imagination, we can download our memories and then upload them into newly baked bodies. All this wildly advanced tech is controlled through touch-activated, transparent, monochrome and often blue holograms. Just like a thousand other futuristic interfaces in Hollywood.

When we are shown a glimpse of the far future through science fiction films, there are omnipresent voice assistants, otherworldly wearables, and a whole lot of holograms. For whatever reason these holograms are almost always blue, floating above desks and visible to anyone who might stroll by. This formula for futuristic UI has always baffled me, because as cool as it looks, it doesn’t seem super practical. And yet, Hollywood seems to have an obsession with imagining future worlds washed in blue light.

Creating 3D objects with sound

Posted by in categories: 3D printing, biotech/medical, engineering, holograms

Scientists from the Micro, Nano and Molecular Systems Lab at the Max Planck Institute for Medical Research and the Institute for Molecular Systems Engineering and Advanced Materials at Heidelberg University have created a new technology to assemble matter in 3D. Their concept uses multiple acoustic holograms to generate pressure fields with which solid particles, gel beads and even biological cells can be printed.

These results pave the way for novel 3D cell culture techniques with applications in biomedical engineering. The results of the study were published in the journal Science Advances.

Additive manufacturing or 3D printing enables the fabrication of complex parts from functional or . Conventional 3D printing can be a slow process, where objects are constructed one line or one layer at a time. Researchers in Heidelberg and Tübingen now demonstrate how to form a 3D object from smaller building blocks in just a single step.

This tech can print 3D objects with sound in ‘one-shot’ process

Posted by in categories: biotech/medical, engineering, holograms

The “one-shot” process paves the path for cutting-edge 3D cell culture methods with biomedical engineering applications, claim the scientists.

German scientists have created a new technology that helps them print 3D objects with sound waves.

The design creates pressure fields using several acoustic holograms, which can be used to print solid particles, gel beads, and even living cells, according to the study released on Thursday.
