FLIR turns the heat up on smartphone thermal imaging

FLIR Systems, Inc. announced two new products at CES designed to put thermal imaging into the hands of consumers. The first is a new, consumer-level infrared thermal camera sensor, while the second is a slide-on attachment for Apple iPhone 5 or 5s smartphones that makes use of said sensor. Both could be used to locate lost pets in the dark, look for energy leaking from your house, or to watch for wildlife.Read More

DARPA developing personal LWIR cameras to give soldiers heat vision

With their ability to pick out humans by their heat signatures, long-wave infrared (LWIR) thermal imaging cameras are a valuable asset for soldiers – and alien predators. Unfortunately, non-alien built ones are expensive and so large that they need to be mounted on vehicles. In an effort to make a LWIR camera cheap and small enough for an individual soldier to carry, DARPA is working on a five-micron camera that offers a reduced size without sacrificing performance.Read More

Perfect optical absorber invented at Harvard University

Harvard Professor of Applied Physics Federico Capasso and his collaborators have invented a nearly perfect optical absorber. By coating a piece of sapphire with an exceedingly thin (180 nm) layer of vanadium dioxide (VO2), a surface is created that absorbs 99.75 percent of infrared light with a wavelength of 11.6 micron wavelength. Such optical absorbers can be tailored to enable a wide range of applications. Read More

Face-scanning cameras could pick out drunks

People who are inebriated in public places (such as airliners or malls) can definitely create problems. Sometimes, though, it’s difficult to tell if someone really is under the influence. Instead of making every “jolly”-looking person take a breathalyzer test, Greek researchers are suggesting something less intrusive – video software that can spot drunks by analyzing their faces.Read More

Turn your iPhone into a networked night vision scope

Imagine if you could turn your iPhone into an advanced night vision recording device, tuned to your every espionage whim. No, there's not an app for that ... but there is the USNV Night Vision iPhone Adapter. Before you get too excited about it, you should note that it doesn't directly turn an iPhone into a night vision scope – you'll still need an actual separate scope. What the NViA does is bridge the iPhone with the night vision scope to leverage iPhone features like video recording, geo-tagging and messaging ... because when you're in the middle of a midnight tail, sometimes you want to go back and scour the footage for more clues – or I assume that you might want to do that, if you were some type of vigilante running around the city with a pair of infrared goggles.

Ultrasound thermography used to find flaws in wood

When choosing wood for applications such as load-bearing beams in houses, it's important not to use pieces that contain cracks or other defects that could affect their structural integrity. While not quite as crucial, it's also nice to avoid flaws when building things like wooden furniture, piano soundboards, or window frames. Typically, people have been limited to visually checking the wood for such defects. Now, however, researchers at Germany's Fraunhofer Institute for Wood Research have developed a system that highlights faults invisible to the human eye, using a process called high-power ultrasound thermography.Read More

Solar panels not just cool for the environment but cool for buildings as well

According to a team of researchers at the UC San Diego Jacobs School of Engineering, the solar panels sprouting on increasing numbers of residential and commercial rooftops around the world aren’t just generating green electricity, they’re also helping keep the buildings cool. The news that letting photovoltaic panels take the solar beating will reduce the amount of heat reaching the roof shouldn’t come as much of a surprise, but the fact no one has thought to quantify just what the effects of rooftop solar panels on a building’s temperature are is a little baffling.Read More

Long-wave infrared driving cameras on the way

The benefits of car night vision systems that enable drivers to see people or animals more clearly on dark, unlit roads have already started appearing in luxury cars. But these systems rely on near-infrared (NIR) radiation, which requires the cars to be fitted with infrared headlights to illuminate the road ahead. Falling into the “thermal imaging region”, Long-wavelength (LWIR) cameras require no such external light source but the sensors require constant cooling, adding to the cost and complexity of such devices. Researchers have now developed a new type of detector which functions at room temperature allowing it to be used in cars and other mobile applications. Read More

Thermoteknix VisIR 640 Thermal Imaging System

I'm pretty sure I'm not the target market for high-end thermal imaging cameras like the VisIR 640 from Thermoteknix, but I want one anyway. I want it in the same way that I desperately wanted the X-ray specs advertised on the back of my Iron Man comics when I was 12. In this case, the object of my boyish compulsion features a 640 x 480 infrared sensor, integrated voice recorder, 1.3megapixel color camera, plus an innovative swiveling lens design which provides greater shooting flexibility, and like many examples of ex-military tech, it opens up a huge range of potential applications on civvy street.Read More
