Packing hundreds of sensors into a single optical fiber for use in harsh environments
By fusing together the concepts of active fiber sensors and high-temperature fiber sensors, a team of researchers at the University of Pittsburgh has created an all-optical high-temperature sensor for gas ...
A better imager for identifying tumors
Before they excise a tumor, surgeons need to determine exactly where the cancerous cells lie. Now, research published today in The Optical Society's (OSA) journal Optics Letters details a new technique that c ...
Skinny lens makes cheap surveillance camera for home use
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 ...
Physicists split and collide ultracold atom clouds (w/ Video)
Physicists at New Zealand's University of Otago have pushed the frontiers of quantum technology by developing a steerable 'optical tweezers' unit that uses intense laser beams to precisely split minute clouds ...
Diagnosis just a breath away with new laser
(Phys.org) —University of Adelaide physics researchers have developed a new type of laser that will enable exciting new advances in areas as diverse as breath analysis for disease diagnosis and remote sensing of critical ...
Force to be reckoned with: Team measures laser power with portable scale
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a novel method for measuring laser power by reflecting the light off a mirrored scale, which behaves as a force detector.
Breakthrough in photonics could allow for faster and faster electronics
(Phys.org) —A pair of breakthroughs in the field of silicon photonics by researchers at the University of Colorado Boulder, the Massachusetts Institute of Technology and Micron Technology Inc. could allow ...
Researchers slow light to a crawl in liquid crystal matrix
(Phys.org) —Light traveling in a vacuum is the Universe's ultimate speed demon, racing along at approximately 300,000 kilometers per second. Now scientists have found an effective new way to put a speed ...
Researchers optically levitate a glowing, nanoscale diamond (w/ Video)
(Phys.org) —Researchers at the University of Rochester have measured for the first time light emitted by photoluminescence from a nanodiamond levitating in free space. In a paper published this week in ...
Seeing depth through a single lens
Researchers at the Harvard School of Engineering and Applied Sciences (SEAS) have developed a way for photographers and microscopists to create a 3D image through a single lens, without moving the camera.
Atomic clock precision could soon be used at home and work
A new development in fibre optic technology could soon bring atomic clock precision to any home or business with a fibre connection, according to researchers at The University of Western Australia and the University of Adelaide.
High-efficiency photon source brings day of reckoning closer for a famous quantum test
(Phys.org) —Physicists working at the National Institute of Standards and Technology (NIST) and the Joint Quantum Institute (JQI) are edging ever closer to getting really random.
New laser shows what substances are made of, could be new eyes for military (w/ video)
A new laser that can show what objects are made of could help military aircraft identify hidden dangers such as weapons arsenals far below.
Lab sets a new record for creating heralded photons
(Phys.org) —Entanglement, by general consensus of physicists, is the weirdest part of quantum science. To say that two particles, A and B, are entangled means that they are actually two parts of an inseparable ...
New tool has potential for brain mapping
A new tool being developed by UT Arlington assistant professor of physics could help scientists map and track the interactions between neurons inside different areas of the brain.
