NASA Funds ‘Tractor Beam’ Study
GREENBELT, Md., Nov. 2, 2011 — Though a mainstay in science fiction, tractor beams may no longer be limited to the likes of our imaginations. Thanks to recent funding awarded to NASA’s Goddard Space Flight Center, three experimental methods for corralling particles and transporting them via laser light to an instrument are now being studied. The NASA Office of the Chief Technologist (OCT) has awarded principal investigator Paul Stysley and team members Demetrios Poulios and Barry Coyle at Goddard Space Flight Center...

Leave the Polar Bears Out of It
Nov 1, 2011 — There are a number of unanswered questions swirling around the so-called “Polar bear-gate” scientific misconduct case, which involves Department of the Interior researchers who published a report of apparently drowned polar bears in the...
Plasmonics, Nanophotonics Hybrid Promises Powerful Information Processing
WEST LAFAYETTE, Ind., Nov. 1, 2011 — Metamaterials and the merging of two technologies under development are promising the emergence of new quantum information systems far more powerful than today’s computers. The technology, which involves a plasmonics and nanophotonics hybrid,...
Fully Featured Machine Vision Software Drives Manufacturing
Nov 1, 2011 — Cameras are ubiquitous on the factory floor, and for good reason: Robots, heavy machinery, raw goods, containers and finished products fly around at breakneck speed, while fewer people than ever are slowing down production by watching over them....
Smart, Self-Healing Fibers Laugh at Danger
Nov 1, 2011 — Light, sturdy fiber optic sensors can help monitor conditions in power plants, on airplane wings, on dams and in other hard-to-reach places. The composition of fiber optic sensors enables them to be placed in areas where traditional point sensors...
Extreme Ultraviolet: A New Frontier for Lasers
Nov 1, 2011 — Advances in compact EUV lasers could benefit industries from semiconductor manufacturing to medicine. Compact lasers that operate in the extreme ultraviolet (EUV) wavelengths – 5 to 50 nm – are poised to offer new abilities to image,...
Aspheric Optics: Ask for What You Want
Nov 1, 2011 — Advances in production make aspheres more readily available and usable at shorter wavelengths, but the methodology is distinctly different from that of spherical optics. It is vital to understand the cost impact of various specifications — and...
Doing What Needs to Be Done
Nov 1, 2011 — I work in an office, but I have a real fondness for the noise and commotion of a manufacturing plant – the energy and activity of things being made – so I was excited to attend the inaugural Lasers for Manufacturing Event (LME), produced...
Cold hands, safe code?
Nov 1, 2011 — Those of us who will soon experience winter’s wrath can perhaps take small comfort in the thought that our cold hands could help deter the theft of our security codes from bank ATMs. You see, warm hands and thermal imaging can help thieves...
Designer surfaces rewrite laws of refraction and reflection
CAMBRIDGE, Mass. – A new technique called phase discontinuity helps light break the age-old laws of reflection and refraction – and could lead to the development of flat lenses that can focus images with no aberrations. For centuries, it has been recognized that...
IR camera senses hot spots to aid firefighters, military pilots
ORLANDO, Fla. – Firefighters and military pilots often use very cold, cumbersome infrared devices to detect hot spots and see through smoke, but a technology that uses gallium nitride (GaN) could eliminate the need for those conventional instruments. Researchers at...
Organic electronics printed on CDs, DVDs
LOS ANGELES – A new patterning technique uses commercially available technology to print conducting polymers using an infrared laser onto standard CDs and DVDs, a feat that could propel current proof-of-concept organic devices – organic LEDs, thin-film...
“Optical switch” could make quantum computers more stable
CAMBRIDGE, Mass. – An optical switch that allows one photon to control the quantum state of another could yield a quantum computer that offers stability and control. Quantum particles have an odd property that enables them to be in “superposition”;...
Squeezed light helps measure gravitational waves
HANNOVER, Germany – A new “squeezed light” method improves the sensitivity and accuracy of the interferometers used to measure gravitational waves. Observing the gravitational waves that result from supernova explosions and other cosmic events requires...
Holographic lithography boosts plasmonic nanogap array production
HOBOKEN, N.J. – A technique based on methods from holographic lithography has been developed to demonstrate a new approach for scaling up the fabrication of plasmonic nanogap arrays while simultaneously reducing costs and infrastructure. A team led by Dr. Stefan...
Universal digital simulator holds promise for quantum computers
INNSBRUCK, Austria – A new digital approach enables universal quantum simulation in a system of trapped ions that can in principle simulate any physical system efficiently, allowing researchers to explore the dynamics of quantum computers. Previously, quantum...
