Voxon’s US$10,000 hologram table – no glasses required

Posted by in categories: augmented reality, holograms, virtual reality

Interactive 3D images that appear to float in the air, above a table that a group of people can stand around without needing any special headsets or glasses: that’s what South Australian company Voxon Photonics has built with its US$10,000 VX1 table.

Fiction has promised us holograms for decades, with one of the most famous examples appearing in 1977’s Star Wars: A New Hope. On board the Millennium Falcon, R2D2 and Chewbacca play some sort of digital board game, interacting with figures built out of light hovering in the air above a table.

Such things have been a long time coming to the real world. VR and AR can both somewhat replicate the experience, but they require headsets. In the best case, these are a bit antisocial, stopping you from looking others in the eye. In the worst case, they completely remove the wearer from the real world to immerse them in virtual space.

Slim-panel holographic video display

Posted by in category: holograms

Holographic displays that are both compact and produce realistic holograms without eyestrain are still difficult to realize. Here the authors implement a steering-backlight unit and a holographic video processor to produce a realistic holographic display in a slim panel.

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

Posted by in categories: climatology, habitats, holograms, 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.
