Imaging at a trillion frames per second | Ramesh Raskar



http://www.ted.com Ramesh Raskar presents femto-photography, a new type of imaging so fast it visualizes the world one trillion frames per second, so detailed it shows light itself in motion. This technology may someday be used to build cameras that can look “around” corners or see inside the body without X-rays.

TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world’s leading thinkers and doers give the talk of their lives in 18 minutes. Featured speakers have included Al Gore on climate change, Philippe Starck on design, Jill Bolte Taylor on observing her own stroke, Nicholas Negroponte on One Laptop per Child, Jane Goodall on chimpanzees, Bill Gates on malaria and mosquitoes, Pattie Maes on the “Sixth Sense” wearable tech, and “Lost” producer JJ Abrams on the allure of mystery. TED stands for Technology, Entertainment, Design, and TEDTalks cover these topics as well as science, business, development and the arts. Closed captions and translated subtitles in a variety of languages are now available on TED.com, at http://www.ted.com/translate

  1. The technology is fantastic. The future is bright (dish-boom). Just think what we have to look forward to, just around the corner (dish-boom). And then at the end Ramesh Raskar asks us to focus (dish boom) on what is coming (dish-boom).

    Mate.That was absolutely the funniest and most enjoyable TED-EX I have ever heard. Thanks a million, or should I say thanks at a Trillion per second (dish-boom).

  2. I too just found this site, though I remember hearing about it some time ago. I'm surprised that there has so far been little impact in the use of this tech, that I have heard of. I notice people commenting that it is of limited use, and I fail to comprehend that reasoning.

    Provided this really works as claimed, I can think of things to look for now. How about the cosmic background radiation? We might see variations indicating contact against another universe, substantially bolstering the multi verse theory.

    Or we might analyze light from exoplanets to detect life signs and maybe even optical viewing. Or closer still, turn it on Mars and see if the refractive signatures indicate water, minerals, maybe even better viewing than a rover. The same with the moons of Jupiter.

    There have been inventions lost before, maybe more than we could ever know. This shouldn't be one of them. Hope someone can breath some life into this, if only now for the sake of art. Art may get it noticed and lead to more.

  8. I wish they did not use the disgusting label of coca cola bottle, and stupid lazy greedy Ted, instead of asking more support money, do not be lazy and put this guy' s link and website, respect his work

  20. Worthless, a waste of time and money. Unjustified over kill. The human eye could never see that fast. If you can't see it, you don't need it. What is next, 12k resolution?? 4K is already too much for human perception. Fools and their money are soon parted.

  27. I was at a Christmas party recently where the magician wowed everybody with his card tricks. It almost made me wonder if my beliefs about certain things were simply false magic, that's how good the magician was.
    But the light is reflected off the coke bottle is still coming at us at the speed of light. All he's doing is taking a bunch of still shots at a very fast speed. Until his camera can take shots at 186k miles per hour, (converted into frames per second) all you are seeing is light in slo-mo. I can show you light in slo-mo. Just take your iPhone and put it into slow motion mode. His camera is just a faster version of the iPhone. Until his camera can slow down light so that it will stop, he has just invented a very fast slo-mo camera. I believe Werner Von Heisenberg would love to have a beer with this guy. But by the time they left the bar, this guy would have to consider a "principle that is highly uncertain".

  31. May be a bit of an over simplification, but radar comes to mind. They are replacing sound waves with light waves. This is by no means a small task. There is a high amount of computing power, algorithms, high end sensors, high end lasers, and many other components required for this to be possible. Not to mention the man and brain power.

  36. quite amazing… you're not just watching the fastest known thing in the universe… but you're also watching the fastest speed the universe will ever allow…. in slow mo. I never would have believed it possible 300,000000m/s …. if you see something going faster than that it's got ET in it. That is so fast that if you saw a pencil keeping up with that light then time on that pencil would be slowed to almost 0 from your perspective… the pencil would be actually squashed in the direction of travel (not squashed as in crushed though… its physical natural length would be reduced)… its mass would be enormous… and the shear amount of energy to get it to that speed would be astronomical. Thats how fast that is. And it would not be that speed.. it would have to be slightly slower.

  39. subliminal mind control during video games shared by mass shooters. it's not the psychotropic drugs that's driving them to do these evil deeds, it's what they can't see because it goes past too fast…but programs their thoughts.
