High speed camera

...CAPTURES THE MOVEMENT OF LIGHT AT FIVE TRILLION PHOTOS PER SECOND

High-speed cameras are certainly useful for slow motion, but they can also find their application in science. Elias Kristensson and Andreas Ehn, researchers at Swedish Lund University, have revealed the world’s fastest high-speed camera. It’s able to capture as many as five trillion frames per second. This sounds astonishing only when you try to read this number, and what’s especially impressive is that camera can visualize the movement of light. It can capture the events as short as 0.2 trillionths of a second.

To demonstrate the speed of this camera, the researchers filmed a group of photons. They are traveling a distance of a paper’s thickness at 671 million mph. Yet, this camera makes it seem as if they’re moving slowly.

I'll have to see how this is possible when they publish a paper about it (the linked article isn't very technical). I'm only skeptical because light is faster than electrons, and any kind of digital camera needs electrons to move around...

Any time you "see" an electron or photon, you change the scene (more like you only see the effects of when they hit something).

If you try to "display" the "position" of an electron or photon relative to something else, like another electron or photon, or a matchbox for scale, you get in complicated trouble.

You can't bounce a laser pulse off a photon. Something lost in translation from Swedish? Like a sarcasm tag somewhere?

Moving this video to lurgee's personal queue. It failed to receive enough votes to get sifted up to the front page within 2 days.
