Mirrors have special powers in the real world too, especially in the hands of an astronomer. In fact, modern astronomy depends on mirrors. Almost every telescope uses a mirror, sometimes several mirrors, to gather and guide starlight toward some super-sensitive digital detector where a breathtaking image can be formed. Without mirrors, it would be almost impossible to study the universe.
Photoacoustic techniques can supplement conventional imaging techniques in breast cancer diagnostics. From first tests on patients using the ¡¥photoacoustic mammoscope¡¦ developed by the University of Twente, researcher Dr. Srirang Manohar concludes that the images obtained add valuable information about the vascularisation of a tumor. The research has been done in cooperation with the Medisch Spectrum Twente hospital in Enschede, and the results are published in the online journal Optics Express.
Raytheon Co.'s operations in Marlborough has won a contract modification for $15.9 million from the U.S. Air Force Research Laboratory to build an array of individual laser 'sub-apertures' that could act as either transmitters or receivers of laser energy, according to the U.S. Department of Defense.
Eblana Photonics Ltd. shipped the first batch of its single-wavelength laser diodes for analog and other ultra-narrow linewidth and low phase noise applications. The product series exhibits RIN down to -160 dB/Hz and emission linewidths below 100 kHz at emitted powers as low as 500 £gW.
A method for mass producing polymer opals that allow novel color-tuning characteristics has been developed by researchers in the UK and Germany. What's more, the researchers believe that they have found a way to make the materials more strongly colored which could open up a range of decorative, sensing, security and photonic applications.
Since Einstein, scientists have dreamed of Laser light powered rockets streaking through space at speeds approaching the speed of light. This vision came a step closer to reality on December 21, 2006, when Dr. Young Bae of the Bae Institute successfully demonstrated the world’s first Photonic Laser Thruster (PLT). Repeated experiments since then have reconfirmed results.
So when Democrats wanted to pass a bill to phase out old-style incandescent light bulbs and require that Americans replace them with more energy-efficient models, they turned to Alaska Sen. Ted Stevens for some GOP support.
The universe's earliest stars may hold clues to the nature of dark matter, the mysterious stuff that makes up most of the universe's matter but doesn't interact with light, cosmologists report.
Prof. Ehud Assia and Dr. Ami Eyel of IOPtima are testing a new laser surgery device specifically designed to make glaucoma procedures safer, simpler and faster.
A regional meeting of experts in Information and Communication Technologies (ICTs) from 23 African countries convene 15-16 September in Pretoria, South Africa, to look for ways on how to harmonise their respective national programmes in implementing the underwater fibre optic project in the Indian Ocean, a reliable source told PANA here Thursday.
Georgian telecommunications provider Caucasus Online and U.S.-based Tyco Telecommunications, an industry pioneer in underseas communications technology, have signed a contract to construct a 1,100-kilometer underseas fiber optic system, which will connect Georgia¡¦s Black Sea port of Poti with the Bulgarian city of Varna.
Cataract patients with no macular pathology can maintain macular integrity after surgery involving a posterior capsulorrhexis and posterior optic buttonholing, according to a surgeon speaking here. Optic buttonholing also produced similar outcomes to conventional in-the-bag IOL implantation, he noted.
Electro-optics companies SCHOTT North America's Fiber Optics Defense Division in Southbridge, Mass., and Clear Align in Eagleville, Pa., are joining hands to design, prototype, and produce electro-optical solutions for defense and security applications.
Oncore Power Systems, of Newport Beach, CA, began producing a line of fiber-optic network cables and cable assemblies. The assemblies can be purchased in 10-Gbit laser-optimized or standard 50-µm multi-mode, 62.5/125 multi-mode, single-mode, and mode-conditioning cables.
anner Engineering Corp. announces the PICO-GUARD(TM) Fiber Optic Emergency Stop Button for use with Banner's PICO-GUARD safeguarding system. The PICO-GUARD E-Stop Button works in conjunction with the PICO-GUARD Controller and other optical elements in personnel safety and equipment protection applications. The E-Stop Button is used with Banner's plastic fiber optic cable and offers a simple, quick means of connecting and disconnecting the fiber. Models are available with fiber entry/exit from either the same side or opposite sides of the housing. When paired with the PICO-GUARD Controller, the E-Stop Button meets Safety Category 4 applications (per ISO 13849-1) and is certified for use in harsh and potentially explosive environments.
