(Phys.org) —Traditional three-dimensional (3-D) plasmonic metamaterials with metallic structures – artificial materials that exploit coherent delocalized electron oscillations known as surface plasmons produced from the ...
In a recent article published in the Review of Scientific Instruments, a research team led by scientists at Lawrence Livermore National Laboratory describe a technique for 3D-image processing of a high-speed photograph of ...
Since the 1960s, theatergoers have shelled out for crude 3-D glasses, polarized glasses, and shutter glasses to enhance their viewing experience. These basic devices, used to trick the brain into perceiving an artificial ...
Nanoscale magnetic swirls known as skyrmions can form in certain materials such as thin magnetic films. These tiny vortices pack into dense lattices that are more stable than conventional magnetic domains and can be transported ...
For decades, since the ability to create a holographic record was discovered, a problem has plagued the field. “In holography,” Tatiana Latychevskaia tells PhysOrg.com, “a twin image unfortunately appears. It is seen ...
As business done over the Internet is becoming almost conventional these days—more banks becoming virtual, more companies going global—information security is something most people take for granted on a daily basis. However, ...
Despite years of hype, virtual reality headsets have yet to topple TV or computer screens as the go-to devices for video viewing. One reason: VR can make users feel sick. Nausea and eye strain can result because VR creates ...
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 ...
Researchers have developed a new approach that improves the image quality and contrast for holographic displays. The new technology could help improve near-eye displays used for virtual and augmented reality applications.
Most of the imaging technologies available today, including smartphone cameras, digital video cameras, microscopes and telescopes, are based on the concepts of direct imaging, i.e., a camera directly recording a scene in ...
