Visualizing video at the speed of light — one trillion frames per second


We have built a virtual, slow-motion camera, where we can see photons, or light particles, moving through space. Now you have seen Doc Edgerton’s pictures of a bullet through an apple. But photons travel about a million times faster than bullets. So our camera can see these photons, or bullets of light, traveling through space. We use a very regular pulsed light source and a camera, that is not one camera, but an array of five hundred sensors, each triggered at a trillionth-of-a second-delay. So, even though each of our sensors is slow, we can still capture fast movie. I’m standing next to our laboratory setup here. This is our camera, objectives in the front here. The body of the camera is much larger than what you would expect from a regular camera, like the one over here. Our light source is a titanium-sapphire laser that’s over here, and emits a beam of very, very short pulses, and those pulses are then directed to the seam [pause] with these mirrors. Now, our camera only sees one dimension so it makes a fast movie, but it makes a fast movie of one line of the scene only And in order to fix that, we have these two mirrors here. We look at the scene via these two mirrors, and when we rotate this upper mirror here we actually see different lines of the scene. So, what’s happening is, the camera keeps taking images and we very slowly rotate this mirror to scan our field of view across the entire scene. And because all of our pulses look the same, we can, in the end, go and combine all of these images that we took to get one complete movie of the scene. Such a camera may be useful in medical imaging in industrial or scientific use, and in the future even for consumer photography. In medical imaging, now we can do ultrasound with light, because we can analyze how light will scatter one-dimentionally inside the body. In industrial imaging, one can use the scattered light to analyze defects in materials. And in consumer photography, we are always fascinated with creating lighting effects that appear to come from very sophisticated light sources. But, because we can watch photons seemingly moving through the space, we can analyze the transport, the movement, of these photons and create new photographs as if we had created those expensive light sources in a studio.

  1. Something is going on here which is beyond the laws of physics. The glow from the particle, is faster than light itself. If you look at the glow through the bottle, it is striking the outside of the plastic and amplifying the liquid, faster than the particle.. so, there's another physical property, which means light is a wave, plus a particle, plus, there's a glow through a medium which in itself is instantaneous it would appear.
    Maybe they're looking into this, but it would appear there's something else going on, which needs to be investigated, as light itself should enter the bottle and you should see the glow as it travels to the skin of the bottle, not an instantaneous illumination as it travels.
    So, a property in light itself and the instant glow across the skin, is in itself faster than the beam as it travels. If anyone at MIT can answer why this is happening, please inform me, because this action in itself would appear to be travelling faster than light. You'd expect to see the beam travel, then the beam slowly make it's way to the skin of the bottle.. this is not happening and this is a total mystery.
    Light slows down as it hits a liquid, so this isn't filming light itself, it's filming a reduced speed of light as it enters the media. I believe the light itself cannot be filmed as it's traveling faster than anything can film.. or else there's a whole new law of physics that this is observing.

  2. This didn't age well…. So many great applications, none of them arrived at 2019. Why would that be?
    From all that we learned about MITML funding, I guess one can draw their conclusions.…

    ps. look up "sugar daddy science" on twitter

  3. So light' speed is basically observer based and it entirely depends on the capacity of the device or the observer. The higher the capacity at which the observer can record across a period of time the faster the record rate of refresh rate of light.

    No wonder why humans are stucked with current value of c².

  4. 😷🤒🤕🤪🤢🤧🤮😱🤪🤪🤪🤪🤪 When I realize YouTube recommended me this video after 7 years.

    I will slap you you you YouTube.

  5. You don't need all the chit… Just stand "farther" out and shine a flash flight and you will see the same thing! 😁😅😁😅😁😅😁😅😁😅😁😅😁😅

  6. his is probably a 99% fake. See the light is just from a normal flashlight moving slowly. If we see this by physics it would take the time from the flash to the apple and then go to the camera, so we will not see the light ray for a distance from the light to the apple. I wonder how these people make others fooled. As the basic thing to catch something you need to be faster than that.

  7. This is amazing, I had no idea this was possible.
    Realizing people figured this out makes me feel like I haven't risen past the chimp phase of evolution.

  8. Bahin Jiv katkatun gela vangyachii bhaji khaun khaun kay karu bahin jivala dhoka karto mi ata aaplyavalya kahi na kahi karunach takin

  9. 24% of NASA employees are from Pakistan. So Indians don't need to be happy by just one Indian in this video.

  10. But to capture the photon on camera, it needs photons from the photon right? 🤯

    Edit: At this speed, we are actually seeing the past of the photon on camera at any point. If you think about it.

  11. Could be used in photography.. Now that would be so epic, like you can take pictures of lightning or use it to add lighting effects in a whole new way.. But photo shop has helped take care of most issues and the fact this kind of camera would be ridiculously expensive lol

  12. I have learnt nothing from this, when that white started talking, i was like blah,blah,blah..u boring.

  13. They're so intelligent to record the speed of light yet too dumb to remove that coke wrapper..

  14. Gamers in the future will demand that games run at a trillion frames per second lol. What for? Doesn’t matter. As long as it does lol.

  15. I see this is an old post but how exactly is this even possible? Even using light in a processor instead of electrons would need several light pulses to control process and record one pulse. So for example all these sequential pulses happen and read and computed before the pulse of light moves a very short distance scatters and makes its way to the camera. How is each bit recorded faster than the speed of light? Something doesnt add up. If this is a reality, Id like to know how this is remotely possible.
