Wearable Sensors that Detect Gas Leaks

Posted by in categories: chemistry, health, holograms, military, wearables

Gas accidents such as toxic gas leakage in factories, carbon monoxide leakage of boilers, or toxic gas suffocation during manhole cleaning continue to claim lives and cause injuries. Developing a sensor that can quickly detect toxic gases or biochemicals is still an important issue in public health, environmental monitoring, and military sectors. Recently, a research team at POSTECH has developed an inexpensive, ultra-compact wearable hologram sensor that immediately notifies the user of volatile gas detection.

New method for producing realistic holograms could enhance virtual reality

Posted by in categories: holograms, virtual reality

The novel optical hologram creating method is three orders of magnitude better than the current ways.

Researchers from the University of Science and Technology of China have developed a new method for creating realistic 3D holographic projections, which is three orders of magnitude better than the current state-of-the-art technology.

The study on the ultrahigh-density method for producing realistic holograms was published in the peer-reviewed journal Optica. Led by Lei Gong, the team developed a new approach to holography that overcame some of the long-standing limitations of current digital holographic techniques.

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.”

Is Our Universe a Hologram? Physicists Debate Famous Idea on Its 25th Anniversary

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.
