Pill-sized device uses spinning laser to image the esophagus

By - January 15, 2013 2 Pictures
Barrett’s esophagus is a precancerous condition typically caused by chronic exposure to stomach acid, and is usually diagnosed by inserting an endoscope down the patient’s throat. A tool has been developed, however, that should allow for a quicker, easier way of getting a good look at such peoples’ esophagus – it’s a swallowable capsule that contains a spinning laser.

Rheinmetall's 50kW high-energy laser weapon successfully passes tests

By - December 20, 2012 3 Pictures
Practical high-energy laser weapons came a step closer to reality in November as Rheinmetall tested its new 50 kW high-energy weapon laser demonstrator. The series of exercises took place at the German-based group’s Ochsenboden Proving Ground in Switzerland. There the 50 kW laser weapon was tested against a series of targets to show the improvements over last year’s 10 kW version. Read More

Nanofocusing device shrinks light beams

By - December 19, 2012 2 Pictures
Engineers at the California Institute of Technology (CalTech) and the University of California at Berkeley have developed a nanofocusing waveguide, a tiny passive plasmonic device which is capable of concentrating light onto a spot a few nanometers in size. In so doing, they have sidestepped the diffraction-limited nature of light, which normally prevents focusing light to a spot smaller than its own wavelength. This remarkable feat may lead to new optoelectronic applications in computing, communications, and imaging. Read More

Prototype robots autonomously strip paint from aircraft using lasers

By - November 26, 2012 15 Pictures
If you think stripping paint off an end table can be a messy, time consuming job, imagine removing paint and other coatings from an aircraft like the C-130 transport plane. Tasked with developing a robotic system that would take such a chore out of the hands of maintenance personnel, Carnegie Mellon University's National Robotics Engineering Center (NREC) and Concurrent Technologies Corporation (CTC) of Johnstown, Pennsylvania, developed a team of robots that gets the job done – using laser beams, no less.

Ultra-sensitive laser-enabled accelerometer could find its way into consumer products

By - October 19, 2012
As any smartphone aficionado knows, the accelerometer is one of the key sensors within the device – it allows the phone to know when and by how much it’s been moved. Accelerometers also have many other applications, being major components of things like navigation systems, various automotive systems, and image stabilization systems in cameras. Now, researchers from the California Institute of Technology are developing a laser-based accelerometer, that they claim should offer much better performance than is currently possible. Read More

Ministry of Defence developing new anti-laser eyewear

By - October 14, 2012 5 Pictures
Laser pointers may be great fun to tease the cat with, but for pilots they are a major hazard. The United States FAA reports over 2,000 incidents every year of planes having lasers pointed at them - some of them powerful enough to pop a balloon. To combat the danger that lasers pose to aviation, the U.K. Ministry of Defence (MoD) is developing new eye wear that can filter out a wide range of laser wavelengths. Read More
