A new type of hologram harnesses a quantum effect and uses ordinary light to make 3-D still images. Future 3-D displays based on this technology would have no need for 3-D glasses or special screens.
The technique is based on the behavior of free electrons on a metal surface, according to researchers at the RIKEN Institute in Japan.
Long gone are the days of pushing plastic armies around hand-drawn maps. Today's military planners deserve technology of the future, and that means nothing less than 3-D holograms will do. Luckily, we have DARPA, ever-ready to step in with a solution.
When we last looked in on holographic telepresence tech, a University of Arizona team was impressively streaming near-real-time three-dimensional moving images, offering a glimpse of what telepresence could be once researchers iron out the wrinkles. Now, an MIT team is showing off a simplified scheme for streaming holographic video, using a single Xbox Kinect peripheral and standard graphics chips to create the fastest holographic video yet.
Videochat is cool enough, but it’s got nothing on R2D2’s 3-D holographic projector (think Princess Leia repeating “Help me Obi-wan Kenobi; you’re my only hope”). Now, a team at the University of Arizona College of Optical Sciences is brining holographic telepresence closer to reality with a new 3-D holographic imaging technology that can record and project a three-dimensional, moving image in real-time without the need for any special eyewear.
When Germany hosted the 2006 World Cup, people flocked to public parks, arenas, and sporting stadiums worldwide to watch the games on massive screens at public viewing events. If Japan lands its bid for the 2022 Cup, you may be able to go to your local soccer stadium and view real-time 3-D hologram displays of tournament games projected full-size on the pitch.
While the first 3-D television sets may start shipping as early as next year, they don't represent true three dimensional images. The televisions require 3-D glasses to work, and only present an image when viewed head on.
What happens when you pop a pill? Inside the University of Calgary's $1.5-million virtual-reality room, scientists can don a pair of 3-D goggles and find out in high-definition detail. Biochemist Christoph Sensen and his colleagues have created a virtual human dubbed the CAVEman (for Automated Virtual Environment) that lets them monitor how a virtual body metabolizes medicine.
