This “Portal” Lets You Beam a Hologram of Yourself Into Video Calls

Shrinking Down

In a bid to sell more than “several dozen” models, the company is now working on a more accessible, miniature version that records and transmits holograms without taking up the entire height of a room. And, company founder David Nussbaum tells TechCrunch, it comes with new subscription features.

Holo-UNet: hologram-to-hologram neural network restoration for high fidelity low light quantitative phase imaging of live cells

Posted by in categories: biological, holograms, robotics/AI

Intensity shot noise in digital holograms distorts the quality of the phase images after phase retrieval, limiting the usefulness of quantitative phase microscopy (QPM) systems in long term live cell imaging. In this paper, we devise a hologram-to-hologram neural network, Holo-UNet, that restores high quality digital holograms under high shot noise conditions (sub-mW/cm2 intensities) at high acquisition rates (sub-milliseconds). In comparison to current phase recovery methods, Holo-UNet denoises the recorded hologram, and so prevents shot noise from propagating through the phase retrieval step that in turn adversely affects phase and intensity images. Holo-UNet was tested on 2 independent QPM systems without any adjustment to the hardware setting. In both cases, Holo-UNet outperformed existing phase recovery and block-matching techniques by ∼ 1.8 folds in phase fidelity as measured by SSIM. Holo-UNet is immediately applicable to a wide range of other high-speed interferometric phase imaging techniques. The network paves the way towards the expansion of high-speed low light QPM biological imaging with minimal dependence on hardware constraints.

Revolutionary Universal Habitats for Earth and Space

This video shows how holographic storage works, using green light to write data as a persistent hologram inside an optical crystal. The data can then be read…How does holographic storage work?


See a home you can live in, make a living out, and grow most of your food in too, the ultimate bug-in or bug-out location — on Mars — here on Earth, or just about anywhere! That is why I call it my Universal Habitat. This is a very low ecological footprint home that can be beautiful, almost no energy cost to maintain, could be built affordably, and be resistant to many natural and man-made disasters such as tornadoes, fire, radiation, and worse. This is the ultimate self-sufficient bunker/fortress.

Scientists Apply Revolutionary 30 Year-Old Principle and Find Black Holes Could Be Like Holograms

Posted by in categories: cosmology, holograms, quantum physics

According to new research, black holes could be like a hologram, where all the information is amassed in a two-dimensional surface able to reproduce a three-dimensional image.

We can all picture that incredible image of a black hole that traveled around the world about a year ago. Yet, according to new research by SISSA, ICTP and INFN, black holes could be like a hologram, where all the information is amassed in a two-dimensional surface able to reproduce a three-dimensional image. In this way, these cosmic bodies, as affirmed by quantum theories, could be incredibly complex and concentrate an enormous amount of information inside themselves, as the largest hard disk that exists in nature, in two dimensions. This idea aligns with Einstein’s theory of relativity, which describes black holes as three dimensional, simple, spherical, and smooth, as they appear in that famous image. In short, black holes “appear” as three dimensional, just like holograms. The study which demonstrates it, and which unites two discordant theories, has recently been published in Physical Review X.

The mystery of black holes.

Black holes are like a hologram

Posted by in categories: cosmology, holograms, quantum physics

The theory of relativity describes black holes as being spherical, smooth and simple. Quantum theory describes them as being extremely complex and full of information. New research now proposes a surprising solution to this apparent duality.

Black holes? They are like a hologram

Posted by in categories: cosmology, holograms, quantum physics

According to new research by SISSA, ICTP and INFN, black holes could be like holograms, in which all the information to produce a three-dimensional image is encoded in a two-dimensional surface. As affirmed by quantum theories, black holes could be incredibly complex, and concentrate an enormous amount of information in two dimensions, like the largest hard disks that exist in nature. This idea aligns with Einstein’s theory of relativity, which describes black holes as three dimensional, simple, spherical and smooth, as depicted in the first-ever image of a black hole that circulated in 2019. In short, black holes appear to be three dimensional, just like holograms. The study, which unites two discordant theories, has recently been published in Physical Review X.

The mystery of black holes

For scientists, pose formidable theoretical challenges for many reasons. They are, for example, excellent representatives of the great difficulties of theoretical physics in uniting the principles of Einstein’s general theory of relativity with those of the quantum physics of . According to the relativity, black holes are simple bodies without information. According to , as claimed by Jacob Bekenstein and Stephen Hawking, they are the most complex existing systems because they are characterized by enormous entropy, which measures the complexity of a system, and consequently contain a lot of information.

Disrupting death: Could we really live forever in digital form?
