Holographic Doctor Visits Astronauts on Space StationNo, it’s not the Doctor from Star Trek: Voyager (though all Trekkies appreciate the Vulcan salute), but he is a real doctor as well as a hologram. Space.com reports that in 2021 NASA flight surgeon Dr. Josef Schmid holographically appeared to astronauts on board the International Space Station. He used software provided by Alexa Aerospace and the Microsoft Hololens Kinect camera while on Earth. This setup allows astronauts and physicians to interact with each other, despite the great distance between them.Space.com says that NASA plans to expand this system for other purposes, including giving the ability of astronauts to “holoport” down to Earth. This could be used to provide private psychiatric care to astronauts as well as permit virtual family visits.The article leaves unsaid the most important question for readers: can Dr. Schmid sing opera?-via Marginal Revolution | Photo: European Space Agency#holograms #holography #astronauts

Researchers Stack "Holobricks" to Generate Large Seamless Holographic 3D ImagesShould this be fully produced and utilized in the future, this newest technology could enable scalable holographic 3D displays. Imagine the possibilities!Developed by researchers from the University of Cambridge and Disney Research, the holobrick is a proof-of-concept tool. The holobrick can tile holograms together to form a large seamless 3D image. The research was done to hopefully provide a way to procure a method for generating high-quality visual experiences. “Delivering an adequate 3D experience using the current technology is a huge challenge,” explained Professor Daping Chu from Cambridge’s Department of Engineering, who led the research. “Over the past ten years, we’ve been working with our industrial partners to develop holographic displays which allow the simultaneous realization of large size and large field-of-view, which needs to be matched with a hologram with a large optical information content.”The holobrick unit was based on a seven-year-old concept developed by CAPE with Disney Research. They utilized the coarse integrated holographic displays for angularly tiled 3D images to form the holograms with large viewing areas and fields of view. Image credit: Li, et.al #research #display #holograms #3D #Disney #UniversityofCambridge #holobrick
