Compact laser system scans road surfaces at 100 km/h

By - May 1, 2013 2 Pictures
Researchers at the Fraunhofer Institute for Physical Measurement Techniques have come up with a car-mounted laser scanner the size of a shoe box, that can survey the contours of road surfaces at speeds of up to 100 km/h (62 mph). The system detects potholes and other road damage in need of repair. According to the Institute, the Pavement Profile Scanner (or PPS) has surveyed 15,000 km of road since mid-2012, in which time it has proven cheaper, faster and more accurate than existing systems which require hefty attachments to the carrier vehicle.

Laser system produces 3D images of objects up to one kilometer away

By - April 11, 2013 2 Pictures
Physicists at Scotland’s Heriot-Watt University have created a 3D imaging camera system capable of resolving depth on a millimeter scale at distances of up to one kilometer. Working much like a laser version of radar, the “Time-of-Flight” (ToF) measurement system “pings” a low-powered infrared laser beam off distant objects and records a pixel-by-pixel map using a detector that counts and positions individual photons as they arrive back at the source.

U.S. Navy to deploy Laser Weapon System on warship

By - April 9, 2013 10 Pictures
The U.S. Navy took a step farther away from John Paul Jones and closer to James T. Kirk as it announced that a solid-state laser weapon will be deployed on a U.S. Navy ship in fiscal year 2014. The announcement that the Laser Weapon System (LaWS) will deployed on board USS Ponce (AFSB[I] 15) two years ahead of schedule was made on Monday at the Sea-Air-Space exposition, National Harbor, Maryland. The deployment is the latest in a line of recent recent high-energy laser demonstrations carried out by the Office of Naval Research (ONR) and Naval Sea Systems Command. Read More

Zapping away cocaine addiction with laser light

By - April 5, 2013 2 Pictures
Like so many other illicit drugs, cocaine can be extremely, destructively addictive. Recent research suggests, however, that ridding people of such addictions may be as simple as zapping them on them scalp. In a study conducted at the National Institutes of Health (NIH), and at the Ernest Gallo Clinic and Research Center at UC San Francisco, scientists were able to turn cocaine addiction on and off in rats via pulses of laser light to their brains.

Scientists propose destroying asteroids with sun-powered laser array

By - February 18, 2013 2 Pictures
This past Friday was not a good day for asteroid-human relations with asteroid 2012 DA14 passing a mere 27,700 km (17,200 miles) from the Earth just a few hours after a meteor exploded over the Russian city of Chelyabinsk, damaging hundreds of buildings and injuring thousands. Scientists have been quick to point out that both of these events – a meteor exploding over a populated area and a large asteroid passing through Earth's geosynchronous orbit – are quite rare, but when the worst case scenario is the complete annihilation of all life on Earth, it's probably best to be prepared. That's why researchers in California recently proposed DE-STAR – a system which could potentially harness the sun's energy to dissolve wayward space rocks up to ten times larger than 2012 DA14 with a vaporizing laser.

Breakthrough laser cooling system could save space and energy

By - February 13, 2013
A research team at Singapore’s Nanyang Technological University (NTU) has successfully used a laser to cool down a semiconductor material known as Cadmium Sulfide. The results of the recently published study could lead to the development of self-cooling computer chips and smaller, more energy efficient air conditioners and refrigerators that don't produce greenhouse gases.

Laser device designed for Mars unmasks counterfeit honey

By - February 13, 2013
When someone mentions counterfeiting, it brings up images of money, watches or DVDs. It certainly doesn't make honey spring to mind, yet honey smuggling and counterfeiting is an international problem involving hundreds of millions of dollars. In an effort to combat this, the European Space Agency (ESA) is funding a demonstration project to adopt lasers designed to study the Martian atmosphere, to detect fake honey. Read More

Scientists turn light into a tractor beam

By - January 28, 2013 3 Pictures
From The Skylark of Space to Star Wars, no self-respecting science fiction spaceship would break orbit without a tractor beam on board. We’re still a long way from locking on to errant shuttlecraft, but a team led by Dr. Tomas Cizmar, Research Fellow in the School of Medicine at the University of St. Andrews, Scotland, has turned a laser into a tractor beam that works on the microscopic level.

Hobbyist builds working replica of Iron Man's laser gauntlet

By - January 21, 2013 4 Pictures
Given that most real-life superheroes don’t have the budget of Tony Stark or Bruce Wayne, you would assume that their gadgetry wouldn’t be quite on par with what we’re used to seeing in the movies. German cyber weapons hobbyist Patrick Priebe recently dropped us a line, however, to tell us about his latest homebuilt creation – a working laser gauntlet, just like the one made famous by a certain Iron Man.
