OSA New thin lens made of silicon opens a door to using less expensive materials for infrared (IR) imaging Dark alleys might not feel so dangerous someday thanks to a new ultra-thin type of lens, which could pave the way to making smaller and cheaper heat-sensing imagers. A team of French researchers has found a way to make a thermal infrared (IR) camera with a lens made of silicon, a much less expensive material than is commonly used today. The new silicon lens is as thick as a...

[ Watch the video: DARPA MOIRE Concept Video ] Lee Rannals for redOrbit.com - Your Universe Online DARPA says it has plans to develop an ultimate spy satellite capable of viewing 40 percent of the Earth’s surface at once. The Membrane Optical Imager for Real-Time Exploitation (MOIRE) space telescope will be launched as a tightly packed cluster of petals 20 feet in diameter, helping it stretch out to 68 feet across. It will record the Earth’s surface with high resolution imagery,...

World's Sharpest X-ray Beam Shines At DESY
2013-09-30 11:42:20

Deutsches Elektronen-Synchrotron DESY The world's sharpest X-ray beam shines at DESY. At the X-ray light source PETRA III, scientists from Göttingen generated a beam with a diameter of barely 5 nanometers – this is ten thousand times thinner than a human hair. This fine beam of X-ray light allows focusing on smallest details. The research groups of Professor Tim Salditt from the Institute of X-ray Physics and of Professor Hans-Ulrich Krebs from the Institute of Materials Physics of the...

The streaming of real-time information across your field of vision is a step closer to reality with the development of a prototype contact lens that could potentially provide the wearer with hands-free information updates. In a study published today, 22 November, in IOP Publishing's Journal of Micromechanics and Microengineering, researchers constructed a computerized contact lens and demonstrated its safety by testing it on live eyes. There were no signs of adverse side effects. At the...

The Contact Lens Of The Future

Contact lenses have been around for decades, correcting vision problems and giving cosmetic or therapeutic aid, but what about using them as a mini-monitor to project text messages or short emails right in front of your eye? Sound like science fiction? Well, according to US researchers at Washington University, the idea of wearing computerized contact lenses is very close to reality. The futuristic technology has taken a step closer with the development of a prototype lens that could...
