World’s Fastest Camera Can ’Capture Light’
Scientists have developed a super- fast camera that can film at an unprecedented rate of five trillion images per second, fast enough to visualise the movement of light.
The camera will be able to capture incredibly rapid processes in chemistry, physics, biology and biomedicine, that so far have not been caught on film, researchers said.
A research group at Lund University in Sweden successfully filmed how light - a collection of photons - travels a distance corresponding to the thickness of a paper.
In reality, it only takes a picosecond, but on film the process has been slowed down by a trillion times.
Currently, high-speed cameras capture images one by one in a sequence, filming 100,000 images per second.
The new technology called Frequency Recognition Algorithm for Multiple Exposures (FRAME) is based on an innovative algorithm, and instead captures several coded images in one picture. It then sorts them into a video sequence afterwards.
The method involves exposing what you are filming (for example a chemical reaction) to light in the form of laser flashes where each light pulse is given a unique code.
The object reflects the light flashes which merge into the single photograph. They are subsequently separated using an encryption key.
The film camera is initially intended to be used by researchers who literally want to gain better insight into many of the extremely rapid processes that occur in nature.
Many take place on a picosecond and femtosecond scale, which is unbelievably fast - the number of femtoseconds in one second is significantly larger than the number of seconds in a persons life-time.
"This does not apply to all processes in nature, but quite a few, for example, explosions, plasma flashes, turbulent combustion, brain activity in animals and chemical reactions. We are now able to film such extremely short processes," said researcher Elias Kristensson.
"In the long term, the technology can also be used by industry and others," Kristensson said.
A regular camera with a flash uses regular light, but in this case the researchers use "coded" light flashes, as a form of encryption.
Every time a coded light flash hits the object - for example, a chemical reaction in a burning flame - the object emits an image signal (response) with the exact same coding.
The following light flashes all have different codes, and the image signals are captured in one single photograph. These coded image signals are subsequently separated using an encryption key on the computer.
5 TOP SECRET PLACES CENSORED ON GOOGLE MAPS
People use Google Earth for various purposes: in order to view satellite images, different maps and terrains, but also 3D buildings, oceans as well as galaxies in outer space. But, have you ever noticed that certain places on Google Earth are completely of limits for the society? Namely, all around the planet Earth, there are ‘secret bases’ that are not edited and are blacked out with purpose with intention to hide whatever is there.Many people would like to find out what are those various ‘censored’ places on Google Maps? Maybe they simply are top secret military bases that belong to different governments around the globe. But, what if those places are much more than military bases? What is the reason so they are censored from Google Maps? What actually is Google trying to hide from the ordinary people?
Well, it seems that as far as it concerns Google, we simply will never find out.
There are numerous places on Google Earth that are edited for special purpose. It seems that the purpose is to prevent users from seeing whatever it is down there. In fact, that is global cover-up and is present all around the earth, in some specific places.
That is something that most people call “global cover-up” and is present all around the globe.
In addition to that, some places including Area 51 are not covered on Google. Some individuals are wondering if is possible that there are secret facilities that are even more secretive than the famous Area 51? Well, there are many other interesting questions: what if these ‘secret bases’ actually do not belong to any government? What if some of these bases do not belong to our – human race?
Below you can watch one interesting video, posted on YouTube by Dark5 that shows five absorbing top secret locations. Namely, these locations have been edited and blacked out in order to cover up and hide something that is there.
But, what could be going on at these sites? What is so much important so Google decided to hide it from the general public? It seems that there are many places on Google that are restricted and erased from satellite images and that makes up to wonder: what else is out there kept away from the general public?
Undoubtedly, we can conclude that seems that our world and society are much more complicated that we can even imagine.
Generally speaking, the governments around the world have done intricately great job and keep certain things away from prying eyes and society. Many of you would agree that many governments around the globe have one thing in common: they all agree that there are “some things” that society or more precisely the ordinary people, should not know about.
Whether it are secret technologies, aliens, some lost ancient structures with inexplicable powers, or simply they are mistakes in satellite images?
What is your opinion? What are these mysterious locations are? Is there something that they are trying to hide? There are many questions and just few answers when it comes to places such these on Google Maps.
Top 5 adventure sports in India
India is gradually becoming a favoured adventure sports destination in the world...
Paragliding is a relatively new sport in India. The major paragliding sites in India are Billing, Kullu, Solang, Lahaul & Spiti(all in Himachal), Naukutchiyatal, Dayara Bugyal, Dhanolti Ridge, Bedni Bugyal (all in Uttarakhand), Jaipur, Jaisalmer, Jodhpur, Udaipur, Bikaner (all in Rajasthan), Matheran, Deolali, Mahabaleshwar (all in Maharashtra). The flying season spans September to December and then March to June. Photo: PTI
Skiing is a big craze worldwide. Gulmarg in Kashmir offers one of the largest facilities for this winter sport. The best part is that the snow conditions remain excellent from December to April. Meanwhile, the slopes in Garhwal and Kumaon are also ideal place for skiing in the winter months. Auli in Garhwal is currently rated as one of India’s best skiing resort. Other places which can be ski lovers delight are Kufri, Narkanda, Manali, Mundali, Munsiyari and Dayara Bugyal. Photo: Getty Images
3. Rock Climbing
Rock Climbing in India assumed the shape of a popular sport nearly a decade ago. Though rock faces, ideal for rock climbing, can be found in many marts of the country, the Aravali range, Western Ghats, Himachal Pradesh and Karnataka provide some of the best climbing faces. Places like Dumdama, Manali and Rohtang Pass are quite popular among rock climbers. The best season for this tricky and risky activity is between October and February. Photo: BCCL
India’s Mountain ranges offer some of the most breathtaking and enthralling trekking routes in the world. The Himalayan foothills are perfectly suited for trekking. The Garhwal and Kumaon regions in Uttarakhand, Chamba and Manali in Himachal Pradesh, and Ladakh and Zanskar in Jammu and Kashmir, are regarded as trekker’s paradise. We can also find some unexplored trekking routes in the North-East. The adventure season covers almost the entire year. Photo: Getty Images
5. White water rafting
The icy Himalayan heights are the source of a major chunk of India's rivers. The intricate network of rivers flowing through rocky gorges and forests are just perfect for adventure sport like the white water rafting. Among the other regions in the country, the Garhwal and Kumaon region in Uttarakhand is regarded as the best location for a perfect water adventure. The most suitable period for this watery extravaganza is between September-November and March- May. Photo: PTI
The Beauty of Finland & Iceland Captured Through Multiple Exposure Landscapes by Mikko Lagerstedt
Spending an entire evening under the stars in near pitch darkness, photographer Mikko Lagerstedt captures spectacular landscapes of frozen tundra and misty mornings of Iceland and his native Finland.
With a camera mounted on a tripod he takes a multitude of exposures as the light gradually changes. Certain elements are then stitched together digitally and enhanced with Photoshop and Lightroom.
The resulting images are a result of hours of photography, editing, and a keen sense of color and composition to create heavily modified images that are almost hyper-realistic. Collected here are a number of landscapes from the last year, but you can see more on Instagram and 500px.
