Scientists dupe infrared cameras with thermal camouflage
Scientists have created a graphene-based material that can outwit thermal cameras by masking hot objects. The film provides a layer of camouflage by appearing to match the ambient temperature, potentially making the object it's covering seem invisible to the cameras.
DJI will let developers fully customize its drones
Drone company DJI is expanding its efforts in the commercial sector with a new thermal imaging camera and a payload software development kit (SDK) that will allow startups and developers to integrate custom gear onto DJI drones.
Yuneec's first commercial drone is ready for filming and rescue
Yuneec may be DJI's biggest consumer drone rival, but you probably have only heard of its consumer and selfie drones. Now, it's taking a step into the big leagues with a new model, the H520. The big, six rotor UAV with bright orange visibility is meant for commercial jobs, including video production, public safety, and inspection. It's equipped with a retractable landing gear, mission planning software and a variety of cameras, including a thermal imaging model and one with a two-inch sensor.
Solar eclipse gives NASA a rare opportunity to study Mercury
While you're stuck on Earth during today's solar eclipse, NASA jets will be performing a tricky science experiment on the Sun and its closest companion, Mercury. A pair of them will take off this morning from Houston's Johnson Space Center and follow the path of of the eclipse, allowing them to see "totality" for three and half minutes, nearly a minute longer than Earth observers. Equipped with a pair of infrared telescopes each, they'll examine the sun's corona and Mercury's chemical signatures to find out what lies below its surface.
Firefighter mask offers hands-free thermal imaging
When firefighters tackle a dangerous blaze, thermal imaging can be their greatest ally. It's usually integrated in a small handheld camera, helping team members to quickly locate civilians, peak through walls and identify safe passageways. Tyco's Scott Safety has now developed a face mask which includes an integrated thermal camera and display, called "Scott Sight." A small image is shown inside the mask -- similar to how Google Glass' would appear in your peripheral vision -- at nine frames per second, for up to four hours. The user can also switch between four different interfaces, as well as ambient and max temperature settings.
DJI has a thermal imaging camera for drones
DJI has announced that it's partnering with FLIR to create a thermal imaging camera for its Inspire 1 and Matrice 100 drones. The Zenmuse XT camera should be a boon for tasks like spotting fires, search and rescue and measuring the thermal efficiency of homes. The drone company is already by far the most popular for cinematographers and hobbyists, but DJI has lately been targeting industrial operations, having recently launched a pesticide-spraying model. The infrared camera could also help farmers monitor crop growth, and would be useful for folks like police, firefighters and building inspectors.
Graphene could bring night vision to phones and cars
Thermal imaging devices like night-vision goggles can help police, search-and-rescue teams and soldiers to pick out bad guys or victims through walls or in complete darkness. However, the best devices require cryogenic cooling, making them heavy, expensive and slow. Enter graphene, the semi-conducting material that's 100 times stronger than steel -- researchers from MIT have built a chip out of the material that may solve the problem. The resulting infrared sensors were small enough that they could be "integrated in every cellphone and every laptop," according to the study's co-author, Tomas Palacios.
New military goggles combine nightvision and thermal imaging
Nightvision and thermal imaging play similar -- but very distinct -- roles on the modern battlefield. Soldiers utilize night vision to illuminate their darkened surroundings while thermal imaging is employed to illuminate darkened targets. But until now, soldiers have had to carry separate imaging systems for each, which negatively impacts how quickly they can switch optics and acquire their targets. BAE Systems, however, announced Monday a new kind of optic that packs the functionality of both into a single unit.
Parrot's new drone keeps its 'head' on straight
Drones are a seemingly everywhere at CES, but senseFly's sensor-laden eXom commercial quadcopter really caught our eye. Why's that? Well, for starters it has a self-leveling and stabilizing err... head up front. That cabeza packs one of five ultrasonic sensors, an ability to record "ultra high-res" stills, HD video and thermal data -- even simultaneously. Like the gizmo's final battery life, weight and price, however, the folks at senseFly, a division of Parrot, aren't ready to talk about exact resolution for any of the cameras. We'd imagine that since the drone's intended to look at pipelines and hydroelectric dams for cracks and defects at close proximity and with "sub-millimeter" accuracy, the imaging tools are going to be pretty powerful.
German railways hope to fight graffiti with thermal imaging drones
Drones aren't just for war, creating airborne logos or patrolling Aussie beaches. If German railway operators have their way, they'd be used to capture graffiti artists, too. Motivated by the high cost of property damage incurred by spray-painting vandals (around 7.6 million euros / $10 million a year), the Deutsche Bahn will soon begin testing miniature helicopter-style drones in the hopes of identifying those responsible. Each remote-controlled chopper is equipped with an infrared sensor capable of thermal imaging and producing high-resolution photos that would be useful to authorities. The tiny aircraft can also fly up to 150 meters (500 feet) and as fast as 33 mph and would cost about 60,000 euros ($77,550) each. The Bahn assured the public that the mini drones will be restricted to highly targeted areas, which should help allay those privacy concerns. [Image Credit: thierry ehrmann, Flickr]
DARPA flaunts HD heat vision camera small enough to carry into battle
Thermal imaging cameras are highly useful tools for military and law enforcement types, letting them see humans inside buildings or land a helicopter in the fog. High-definition models are too heavy for servicemen to tote, however, so DARPA and a private partner have built a 1,280 x 720 LIWR LWIR (long-wave infrared) imager with pixels a mere five microns in diameter. That's smaller than infrared light's wavelength, allowing for a slighter device without giving up any resolution or sensitivity while costing much less, to boot. Researchers say that three functional prototypes have performed as well as much larger models, allowing them to see through a simulated dust storm, among other tests. If DARPA ever lets such goodies fall into civvy hands, count us in -- you can never have too much security.
Scientists develop pair of algorithms that could enable thermal cameras to pick out drunk people
We're not sure if Georgia Koukiou and Vassilis Anastassopoulos of the University of Patras in Greece like a tipple or not, but the pair have developed two algorithms that, when used with thermal imaging, could pick out drunk people in crowds. What is it that betrays your best intentions to look sober? As always, your face. Booze causes the blood-vessels in your visage to dilate, and the researchers used this principle to compare facial scans against a database of tipple-free mug shots. Likewise the duo found that when under the influence, the nose gets warmer, while the forehead cools -- another visual check that the infrared can help identify. The hope is that using this technology, law-enforcement can make a judgement call based on more than just your wonky walk. But in our experience, the troublemakers are pretty good at outing themselves.
Modder builds $150 open-source thermal imaging camera to help insulate his house (video)
Modder Andy Rawson thinks he's found the secret to turning smartphones into super-cheap thermal imaging hardware. Inspired by his quest to find leaks in his old home and the high cost of professional gear, he set about building his own. A 64-zone temperature sensor connects to his iPhone via the dock, overlaying the data onto his camera display. He's planning to open-source the $150 hardware, and an Android variant of the hardware is currently in the works -- although details for both are currently thin on the ground, you can see his announcement video after the break.
Researchers working on thermal cloak, Predators trill their disapproval
Slathering yourself with mud to avoid head-hunting aliens is great and all, but it ain't exactly the paragon of good personal hygiene. Fortunately, researchers have concocted a cleaner and less cakey defense against Predators that's more likely to be mom approved. Fresh on the heels of the microwave invisibility project at the University of Texas at Austin, French researchers have found a way to make a cloak that can hide a subject from thermal imaging devices. The concept uses alternating materials with varying rates of diffusion to move heat around and create a thermally invisible region. Conversely, the technique can be used to concentrate heat in one spot so it gets hot rapidly. Although it doesn't quite have the wow factor of Cornell's invisibility project, the thermal research may prove to be more practical because it also can be used to manage heat and improve cooling in components such as computer chips. Of course, the question now is, can it be used to cloak an entire tank?
GE turns butterfly-inspired tech into cheap, accurate thermal sensors (video)
When last we heard from GE and its Morpho-butterfly inspired sensors, all the talk was about detecting chemicals. And, with $6.3 million in funding coming from DARPA, we're not surprised. In the latest issue of Nature Photonics, however, the company's researchers show that the wing-like structures are just as good at detecting heat as they are ricin attacks. By coating them with carbon nanotubes the team was able to create a sensor sensitive to temperature changes as small as 0.02 degrees Celsius with a response rate of 1/40 of a second. The sensors could eventually find their way into imaging devices and medical equipment, and are expected to cost just a fraction of similar technologies currently on the market. Of course, since DARPA is still involved with the project, there are some potential security uses as well -- such as screening devices and fire detection. Head after the break for a video and some PR.
BAE's infrared invisibility cloak makes tanks cold as ice, warm as cows
Warfare's constantly evolving. Daylight battles became late-night duels, and pre-noon skirmishes shifted to sundown slaughters -- some might say we're just getting lazy, but either way, thermal imaging now plays quite the vital role. Now BAE and the FMV -- Sweden's equivalent to DARPA -- have a way to mask the heat signature of heavy machinery. Adaptiv is a wall of 14 centimeter panels that monitor the ambient heat and match it, so it can't be picked out from the background radiation. The tech can also be used to replicate the profiles of other things -- you know, like a spotted calf or a Fiat 500. BAE believes the tech is scaleable for buildings and warships, the only downside being that all future commanders will have to make sure their operations are finished before dawn. Wouldn't want your soldiers to see that five o'clock (AM) shadow, now would we? [Thanks, Rob]
Termibot robot exterminator kills termites, heralds terrifying future
Termites be warned: Australian outfit Termicam is bringing the noise Predator-style with the Termibot, a dual-tread thermal imaging robot designed to eliminate insects. The bot scoots around inside walls and under houses relaying information from its thermal camera and moisture sensors back to an operator, and when termite (or other insect) activity is detected, it uses a probe to smash the nest and inject pesticides directly where they're needed. While we're not certain we need to help robots perfect the techniques they'll use to ferret out the last remnants of the human resistance, we're not too worried yet -- the Termibot is currently tethered to its operator with a long cable. The designer says a fully wireless version is in the works and will be brought to market later this year, however -- it's being held up while the business experiences some growing pains. Termicam also says they're also looking to expand the uses for the bot to other applications where that thermal camera might come in handy, like bomb disposal and search and rescue -- looks like the PackBot's got some competition.[Via Crave]
