Math professor's side mirror that eliminates 'blind spot' receives US patent
A side mirror that eliminates the dangerous "blind spot" for drivers has now received a U.S. patent. The subtly curved mirror, invented by Drexel University mathematics professor Dr. R. Andrew Hicks, dramatically increases ...
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.
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 bump in light's ...
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.
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 could give surgeons ...
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.
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.
No more blind spots: Researchers design new rearview mirror
(Phys.org)—A new optical prescription for automobile side-view mirrors may eliminate the dreaded "blind spot" in traffic without distorting the perceived distance of cars approaching from behind. As described in a paper ...
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.
Researchers create novel optical fibers
(Phys.org) —Researchers at the University of Wisconsin-Milwaukee (UWM) have found a new mechanism to transmit light through optical fibers. Their discovery marks the first practical application of a Nobel-Prize-winning ...
