We posted before about this technology, but now we have a brilliant TED talk from one of the researchers from MIT, Ramesh Raskar, explaining all about it.
Femto photography, computational photography, that’s highly advanced stuff and it’s implications go well beyond the world of photography and video.
1 trillion frames per second, wow!
Take a look and be amazed:
From the description:
In 1964 MIT professor Harold Edgerton, pioneer of stop-action photography, famously took a photo of a bullet piercing an apple using exposures as short as a few nanoseconds. Inspired by his work, Ramesh Raskar and his team set out to create a camera that could capture not just a bullet (traveling at 850 meters per second) but light itself (nearly 300 million meters per second).
Stop a moment to take that in: photographing light as it moves. For that, they built a camera and software that can visualize pictures as if they are recorded at 1 trillion frames per second. The same photon-imaging technology can also be used to create a camera that can peer “around” corners , by exploiting specific properties of the photons when they bounce off surfaces and objects.
Among the other projects that Raskar is leading, with the MIT Media Lab’s Camera Culture research group, are low-cost eye care devices, a next generation CAT-Scan machine and human-computer interaction systems. “Though photographs in the near future will still be composed by people holding cameras, it will gradually become more accurate to say pictures were computed rather than ‘taken’ or ‘captured.’”

Photography is about creating images by recording light. Ramesh Raskar has invented a camera that can photograph light itself as it moves at, well, the speed of light.
