Oxford Instruments to Auction Off Patents
CHICAGO, March 10, 2011 — Technology patents from Oxford Instruments will be auctioned off at ICAP Ocean Tomo’s Spring 2011 Live IP Auction on March 31 in New York City. The related lots to be sold include patents involving an imaging system and a microbolometer. Oxford Instruments has determined that these patents are no longer useful for its ongoing business. Advanced imaging patent Object detection systems are widely used at airport terminals and commercial buildings, but conventional systems...
Optical Tweezers: There’s an App for That
LONDON, March 9, 2011 — A multitouch holographic optical tweezers interface for the iPad lets even novice users move and manipulate tiny particles like a pro.
Photon-Detection Records Set
WALTHAM, Mass., March 9, 2011 — Excelitas Technologies Corp. has announced record photon-detection efficiency and low dark counts in its solid-state silicon photomultipliers, low-light-level detection devices, with applications in medical and analytical markets. In 2009, the...
Laser Suturing Coming Soon to the OR
MUNICH, Germany, March 7, 2011 — A new minimally invasive tool that closes wounds using a laser takes its inspiration from a laser welding process developed for plastics. Although more and more surgeries are being carried out in a minimally invasive manner, the suturing of...
Sheets of Light Image Live Cells
ASHBURN, Va., March 7, 2011 — Using an exquisitely thin sheet of light, a newly developed microscope reveals the 3-D shapes of cellular landmarks in unprecedented detail. The technique images live cells at high speed so that researchers can create dazzling movies that make...
LED Advance to Mean Freedom from Binning
SAN JOSE, Calif., March 4, 2011 — A new advance from Philips Lumileds is promising to simplify the design process for LED solutions, which could mean an end to the binning process. The company said its Luxeon LEDs are tested and binned in real-world operating conditions so that...
MMIs Targeted for Quantum Computers
BRISTOL, England, March 4, 2011 — Quantum circuits based on optical multimode interference (MMI) are being used to advance quantum computers. Building a quantum computer will require a large number of interconnected components (gates), whose function is similar to that of a...
‘Superskin’ Goes Solar
STANFORD, Calif., March 3, 2011 — An ultrasensitive electronic skin has been developed that can detect chemicals and biological molecules in addition to sensing an incredibly light touch. What’s more, this new “superskin” can be powered by stretchable solar cells,...
Microscope Beats Diffraction Limit
MANCHESTER, England, March 3, 2011 — A microscope created by scientists at the University of Manchester shatters the record for the smallest object the eye can see, beating the diffraction limit and likely helping to elucidate the causes of many viruses and diseases. Experimental...
SERS Advances Disease Diagnosis
DURHAM, N.C., March 3, 2011 — Scientists at Duke University have developed a new noninvasive optical technique that uses a laser to peer into the genetic material of cells, enabling the detection of early-stage cancer and other diseases. The method uses metallic nanoparticles...
“Liquid pistons” advance camera lenses
TROY, N.Y. – A few unassuming drops of liquid locked in a very precise game of “follow the leader” could one day be found in mobile phone cameras, medical imaging equipment, implantable drug-delivery devices – possibly even implantable eye...
A new technique for terahertz radiation
BOULDER, Colo. – A new laser-based source of terahertz radiation that is more efficient and less prone to damage than similar systems could be useful for detecting trace gases or imaging weapons in security screening. Researchers at JILA, a joint institute of the...
Atmospheric laser propagation
WASHINGTON – An underwater photo-ionization laser acoustic source developed by researchers at the US Naval Research Laboratory could enable remote acoustic generation from compact air- and shipborne lasers, allowing aircraft to communicate without the need for...
Carbon nanotubes as optical antennae
ITHACA, N.Y. – Researchers at Cornell University have found that carbon nanotubes’ light transmission behaves as a scaled-down version of radio-frequency antennae found in walkie-talkies, except that the interaction is with light instead of radio waves. The...
Compact brilliant laser light source developed
BERLIN – Scientists from Ferdinand-Braun-Institut have developed small, brilliant laser light sources that provide significantly smaller systems for laser projectors and other display technologies. After watching a roller-coaster ride in a film, Dr. Katrin...
E-beams get a new twist
GAITHERSBURG, Md. – A new method to expand the capabilities of conventional transmission electron microscopes (TEMs) has been discovered by researchers at the National Institute of Standards and Technology. Passing electrons through a nanometer-scale grating imparted...
Electrons “synch up” to form superconductors
OXFORD, UK – One hundred years after superconductivity was first observed in 1911, a team of researchers has used laser light to transform a nonsuperconducting material into a superconductor. Superconductivity – a phenomenon in which an electric...
Femtosecond laser reaches kilowatt range
AACHEN, Germany – An amplification concept developed for femtosecond lasers has enabled researchers to achieve mean power in the kilowatt range for the first time. The scientists, from Fraunhofer Institute for Laser Technology, have taken a step that could expand the...
Hydrogels Form Precise Sensor
WEST LAFAYETTE, Ind., March 1, 2011 — Researchers are developing a new type of biological and chemical sensor that has few moving parts, is low-cost and yet highly sensitive, sturdy and long-lasting. The "diffraction-based" sensors are made of thin stripes of a gelatinous material...
Laser analysis used for mining
AACHEN, Germany – As demand for minerals and other natural resources increases, so does the need for optimizing mining techniques. Fraunhofer Institute for Laser Technology has developed a laser analysis system that can identify potential mineral reserves. As...
Laser/Ion-Funnel Mass Spec Mars-bound?
RICHLAND, Wash., March 1, 2011 — Finding life on Mars could get easier with a creative adaption to a common analytical tool that can be installed directly on the robotic arm of a space rover. In a recent paper published online in the journal Planetary and Space Science, a...
Nanostructures caught on film
BERLIN – A picture may be worth a thousand words, but a movie comprising several pictures can tell you about an object’s dynamics. Scientists at Helmholtz-Zentrum Berlin für Materialien und Energie and at Technische Universität Berlin...
Optical materials go designer
AMES, Iowa – Advances in fabrication technologies could one day lead to superlenses and other designer optical materials. Scientists at Iowa State University and at Karlsruhe Institute of Technology in Germany are studying exotic man-made materials designed to...
Sniffing out bombs and pollutants from a distance
PRINCETON, N.J. – A breakthrough in laser sensing technology could allow soldiers to detect hidden explosives from a distance and scientists to better measure airborne environmental pollutants and greenhouse gases. The new laser sensing technology developed by...
Supercharged FEL Blasts Through Steel
WASHINGTON, March 1, 2011 — The Navy's Free Electron Laser (FEL) has set a record for power generation, blasting through steel at a rate of 20 feet per second, Fox News reported. A test blast revealed that the FEL can shoot cruise missile from the sky in seconds with an...
