Right now it looks like the graphics from Nintendo’s Virtual Boy, but the engineers want to add full color.

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.

Base Hologram has made its mission clear: create premium holographic shows. But will the ethical questions surrounding holograms keep it from success?

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.

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.

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.

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.
