Once, holograms were just a scientific curiosity. But thanks to the rapid development of lasers, they have gradually moved center stage, appearing on the security imagery for credit cards and bank notes, in science fiction movies—most memorably Star Wars—and even “live” on stage when long-dead rapper Tupac reincarnated for fans at the Coachella music festival in 2012. …

Intel Shuts Down Its AR/VR Volumetric Capture Stage
Intel has pulled the plug on one of its most ambitious AR/VR projects to date: The company quietly shut down Intel Studios, a 10,000-square-foot volumetric capture stage in Los Angeles, last month. The facility had been heralded as the world’s largest capture stage of its kind, and was used to record music videos for Reggie Watts and K-pop band NCT 127,…
Samsung: Expect 6G In 2028, Enabling Mobile Holograms and Digital Twins
An anonymous reader quotes a report from VentureBeat: [A]s 5G continues to roll out, 6G research continues, and today top mobile hardware developer Samsung is weighing in with predictions of what’s to come. Surprisingly, the South Korean company is preparing for early 6G to launch two years ahead of the commonly predicted 2030 timeframe, even though both the proposed use cases…
Black holes are like a hologram
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. Source: https://earthsky.org/space/black-holes-are-like-a-hologram…
Black holes? They are like a hologram
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….
The BBC’s 1992 TV Show About VR, 3D TVs With Glasses, and Holographic 3D Screens
dryriver writes: 27 years ago, the BBC’s “Tomorrow’s World” show broadcasted this little gem of a program [currently available on YouTube]. After showing old Red-Cyan Anaglyph movies, Victorian Stereoscopes, lenticular-printed holograms and a monochrome laser hologram projected into a sheet of glass, the presenter shows off a stereoscopic 3D CRT computer display with active shutter glasses. The program then takes us…
Ask Slashdot: What Happened To Holographic Data Storage?
dryriver writes: In an episode of the BBC’s Tomorrow’s World broadcasted all the way back in 1984, a presenter shows hands-on how a laser hologram of a real-world object can be recorded onto a transparent plastic medium, erased again by heating the plastic with an electric current, and then re-recorded differently. The presenter states that computer scientists are very interested in…
We can now make animated ‘sound holograms’ that you can touch
Using a polystyrene bead, some speakers and a handful of LEDs, it is possible to make colourful animated 3D holograms that a user can touch and interact with Source: https://www.newscientist.com/article/2223325-we-can-now-make-animated-sound-holograms-that-you-can-touch/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
3-D holograms bringing astronomy to life
Scientists working on unravelling the mysteries of star cluster formation have found an innovative way of sharing their work with the general public. Taking inspiration from a 19th century magic trick, researchers from the University of Leeds have developed 3-D holograms that allow people to watch massive stars forming before their eyes.
