Researchers at UCLA have built a cheap, optics-free holographic microscope capable of detecting bacteria like E. coli in things like water, food, and blood. And by cheap, we mean really cheap. The researchers say it costs less than $100 to build.
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.
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.
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.
