New transparent, flat, flexible image sensor has potential for gesture control displays

By - February 21, 2013 2 Pictures
A research team from the Johannes Kepler University Linz in Austria has developed an image capturing device using a single sheet of polymer that is flat, flexible and transparent. The researchers say the new image sensor could eventually find its way into devices like digital cameras and medical scanners, and that it may help to usher in a new generation of gesture-controlled smartphones, tablets and TVs.

MIT's new image-processing chip improves digital snapshots

By - February 19, 2013 2 Pictures
Snapshots banged off on a smartphone, tablet or point-and-shoot camera could soon be getting a lot better looking thanks to a new processor chip. Developed by researchers at MIT’s Microsystems Technology Laboratory, the new chip enhances images within milliseconds, and reportedly uses much less power than the image processing software installed on some devices.

DARPA's new 1.8-gigapixel camera is a super high-resolution eye in the sky

By - February 11, 2013 8 Pictures
DARPA recently revealed information on its ARGUS-IS (Autonomous Real-Time Ground Ubiquitous Surveillance Imaging System), a surveillance camera that uses hundreds of smartphone image sensors to record a 1.8 gigapixel image. Designed for use in an unmanned drone (probably an MQ-1 Predator), from an altitude of 20,000 ft (6,100 m) ARGUS can keep a real-time video eye on an area 4.5 miles (7.2 km) across down to a resolution of about six inches (15 cm).

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.

Quantum-enhanced radar can't be fooled by electronic detection countermeasures

By - January 10, 2013 2 Pictures
The military use of radar has always had a yin-yang dynamic – as new forms of radar are developed, so too are new ways to jam them. A team of physicists at the University of Rochester has discovered how to defeat the latest active radar jamming methods by taking advantage of the quantum properties of photons. While this new anti-jamming technology cannot remove the false information, it provides an immediate alert that false information is being received. Read More

Cheap, compact chip could expand T-ray scanning potential

By - December 12, 2012 3 Pictures
Terahertz technology (or T-Ray, for short), sounds like something out of a science fiction movie. It utilizes high-frequency terahertz waves – which are located between microwaves and far-infrared radiation on the electromagnetic spectrum – to see through solid matter without the harmful ionizing radiation of X-rays. Although T-Ray devices have yet to become compact and affordable, that could soon change thanks to new silicon microchips developed at the California Institute of Technology. Read More

NORUSCA II camera sheds new light on auroras

By - November 29, 2012 5 Pictures
Even those of us not lucky enough to have witnessed them in person will likely have marveled at photos of the stunning auroras caused by high energy particles from the Sun colliding with atoms in the Earth’s atmosphere. A team of space-weather researchers has now developed a new camera called NORUSCA II that has produced the first-ever hyperspectral images of the aurora borealis (or northern lights) and may have uncovered a previously unknown atmospheric phenomenon.

Cold mirror makes hot astrophotos a snap

By - November 14, 2012 9 Pictures
While nearly everyone enjoys a good astrophoto, the precision with which the astrograph (the telescope taking the photograph) must follow the stars is not widely appreciated. To take a good astrophoto of any but the brightest objects requires following their motion through the sky accurately. There are a number of approaches toward addressing this problem in the digital era. Perhaps the best option has now been enabled by Innovations Foresight's new ON-Axis Guider (ONAG). Read More

Hand-held 3D scanner could simplify medical imaging

By - October 2, 2012 2 Pictures
Although there are various efforts under way to create a working Star Trek-like medical tricorder, such a device isn’t available for general use just yet. In the meantime, however, doctor’s offices may soon be equipped a piece of equipment that wouldn’t look at all out of place in the sick bay of the Enterprise. Developed by engineers from the University of Illinois at Urbana-Champaign, it’s a hand-held scanning device that provides real-time three-dimensional images of the insides of patients’ bodies.

Dark Energy Camera captures its first images

By - September 19, 2012 17 Pictures
The Dark Energy Camera (DEC) has captured an initial batch of images as part of an ongoing quest to afford scientists with a better understanding of dark energy. The images were taken by the 570-megapixel behemoth from its location within the Chilean Andes on September 12 while undergoing a series of tests. Scientists hope it may soon help answer one of the biggest mysteries in physics: why the expansion of the universe is speeding up. Read More
