    Why does IAB keep posting these dumb vids? They are drating boring and serve no purpose in this world.

    MIT researchers, postdoctoral researcher Andreas Velten along with associate professor Ramesh Raskar have created a new imaging system that can acquire visual data at a rate of one trillion exposures per second. Is it the same invention ?LINK

    It`s cool that there`s a camera that shoots a trillion frames per second, but it`s not cool that they used it for....ahem...this.

    i need a little more context than this. i can shoot that on my phone. where does this huge frame rate come in? and when would you use it? maybe to see atoms split, but that`s about it.

    Ok, I use this site every day for a little entertainment. And I`ve never felt the need to comment on something till now. This is amazing! The camera is actually able to capture light in motion, there`s another video of light moving through water which is pretty neat as well.

    No offense, but the people who don`t understand why this is amazing are retarded... IT`S FILMING LIGHT AT THE SPEED OF LIGHT, FFS. If you were to watch this at normal speed, you would simply see a light being turned on and illuminating an apple, which would appear to be instantaneous. The whole point is that you are actually seeing light move from the light source to its destination, moving at 3*10^8 m/s! The person who said he could shoot this on his phone isn`t too bright...

    That`s a bit harsh phobophobia. I understand it has great scientific implications but really, to the average person watching it just looks like someone sweeping a flashlight beam across a piece of fruit while filming. It`s pretty unspectacular.

    It`s pretty cool how you can see the light ripple on the wall behind the apple.

    I come from a family of photographers so I find this amazing. I was blown away by the works of "Doc" Edgerton (Google him, you`ve seen his pictures). This is like exponential Edgerton!

    I have officially lost hope in the human race that people don`t find this absolutely astounding. I have a feeling that movies like Idiocracy and Wall-e hit the nail right on the head.

    @indisguise Lets see you make a video of waving a flash light over a tomato and see if its anywhere close to this. For something that you can`t see through all too well, its not that cool, but the bottle of water that was up not too long ago and other translucent and transparent materials are astounding. I also want to point out that this video is in 1080p, but it looks like its 360p. Whats up with that?...

    Assuming 2 million pixels and 16 bit colour (both rather low figues), that`s 4x10^18 bytes per second. 4 exabytes per second. How on earth do you deal with that amount?

    We`ve all seen slow motion video of various things, when movement is filmed at a high framerate and played back at ~25fps.

    I now have an image in my head of this being used for slow motion video.

    An eyeblink filmed at this speed and played back at 25fps would take about 400 years to show the full blink.

    WTF? Have I got that wrong? Someone check my numbers, please.

    Angilion, you`re not wrong,
    I don`t know how long a blink is, but I calculated for a second, and I got around 1268 years for filming at 1 trillion fps, played at 25 fps.

    anyway, as amazing as light waves are, this video just makes me think about how expensive a trillion fps capturing camera is....

    A blink is ~300ms, so we are getting the same numbers. Wow. I thought maybe I`d botched something and was out by entire orders of magnitude.

    If they could actually get video, there must be some applications for it. Normal high speed video has been useful for examining larger-scale objects in motion and that`s given researchers some fresh insight. Who knows what such high speed video could shed new light on?

    But I`m still wondering how they could deal with the rate of data at that speed.

    The laser pulse is about 50 picoseconds (10-12 second) It can be measured by the width of the light pulse seen( approximate 1.5cm) thats how far the light can travel in that time.
    If the camera records in 1 trillion fps then it will capture about 20 frames for every 1.5 cm we have.
    So if the fruit is 5cm long the full frame is about 15cm so the total of frames in this video would be 200 frames.
    So not a big deal to store.
    I you dedicate a different storage stream for each frame you can save them with no problem the only limitation is your budget.

    "anyway, as amazing as light waves are, this video just makes me think about how expensive a trillion fps capturing camera is...."

    Especially since its not recording an entire second. its recording an instant, the time it takes for light to travel.

    The past one of these ive seen was actually a series of mirrors lined up, as each frame was burnt in the mirror was broken as to not transmit any more of the light....

    "It`s cool that there`s a camera that shoots a trillion frames per second, but it`s not cool that they used it for....ahem...this."

    ......and what else do you know that moves at the speed of light? Cynical much?

    "well i was hoping for something cool to happen. Thanks for the letdown. in other words,
    Nothing to see here, move along"

    Yeah god forbid we have cool videos of stuff you like, like stocking shelves and pumping gas....
