Researchers combine lasers and terahertz waves in camera that sees ‘unseen’ detail

The time-resolved nonlinear ghost imaging camera uses a nonlinear crystal to convert standard laser light to terahertz patterns, allowing the reconstruction of complex samples using a single terahertz pixel.

A team of physicists at the University of Sussex has successfully developed the first nonlinear camera capable of capturing high-resolution images of the interior of solid objects using terahertz (THz) radiation.

Led by Professor Marco Peccianti of the Emergent Photonics (EPic) Lab, Luana Olivieri, Dr. Juan S. Totero Gongora and a team of research students built a new type of THz camera capable of detecting THz electromagnetic waves with unprecedented accuracy.

Images produced using THz radiation are called ‘hyperspectral’ because the image consists of pixels, each one containing the electromagnetic signature of the object in that point.

AI : The future of photography ?

How machine learning and artificially generated images might replace photography as we know it.

When hearing the words ‘AI’, ‘Machine Learning’ or ‘bot’ most people tend to visualize a walking, talking android robot which looks like something out of a Sci-Fi movie and immediately assume about a time far away in the future.

A Chinese company said it created a photo with such a high resolution that you can zoom from thousands of meters away to see people’s facial expressions

You might call this the pinnacle of high-resolution images.

  • The image, the brainchild of a company called Jingkun Technology, or BigPixel, was taken from atop the Oriental Pearl Tower in Shanghai, China.
  • The company said the photo’s resolution is a mind-blowing 195 gigapixels.
  • The resolution of digital cameras and smartphones is often measured in megapixels, or 1 million pixels — so a 12-megapixel camera, for example, can produce images with 12 million total pixels. But in this case we’re talking about gigapixels, or 1 billion pixels.

At 10 trillion frames per second, this camera captures light in slow motion

IMG_9471

Light is the fastest thing in the universe, so trying to catch it on the move is necessarily something of a challenge. We’ve had some success, but a new rig built by Caltech scientists pulls down a mind-boggling 10 trillion frames per second, meaning it can capture light as it travels along — and they have plans to make it a hundred times faster.

Understanding how light moves is fundamental to many fields, so it isn’t just idle curiosity driving the efforts of Jinyang Liang and his colleagues — not that there’d be anything wrong with that either. But there are potential applications in physics, engineering, and medicine that depend heavily on the behavior of light at scales so small, and so short, that they are at the very limit of what can be measured.

You may have heard about billion- and trillion-FPS cameras in the past, but those were likely “streak cameras” that do a bit of cheating to achieve those numbers.

People will take 1.2 trillion digital photos this year — thanks to smartphones

IMG_3376

Thanks to smartphones, millions of people around the globe are turning into prolific photographers. According to estimates from InfoTrends, people will take a hundred billion more photos in 2017 than they did in 2016. As highlighted by this chart from Statista — which is based on the InfoTrends’ data — the vast majority of those photos will be taken on smartphones.

Researchers at MIT have developed a new camera that can photograph a trillion frames per second. Compare that with a traditional movie camera which takes a mere 24. This new advancement in photographic technology has given scientists the ability to photograph the movement of the fastest thing in the Universe, light.

The Laws of Exponential Capabilities

Laws-of-Exponential-Capabilities-1

Futurist Thomas Frey: When people like Google CEO, Larry Page, Virgin’s Richard Branson, and X-Prize Foundation CEO, Peter Diamandis, talk about us entering into a period of abundance, there has been a natural tendency to assume we’ll be entering into a life of leisure. People won’t have to work as hard and we will all have more time for travel, vacations, and play.
