cool! must be some kind of composite video from multiple samples? I mean, we're not looking at a single photon here or a single pulse of a laser.

That’s right

Any idea how fast the shutter would have to be moving? Or the diameter of the aperture so we can calculate it!

I would tend to think that it's an electronic shutter, but I'd be happy to be corrected

This is kind of misleading: they didn’t capture 1 trillion frames. At least not in one go. The video was composited from many, many very well-timed streak camera images, repeating the light pulses for an hour. http://news.mit.edu/2011/trillion-fps-camera-121 … Still though, this is incredibly cool.

this is a technique commonly used in many sampling systems. Instead of using a ridiculously high sampling rate which is expensive or impossible, when one is looking at a periodic wave, one samples with adjusted phases and reconstructs from measurements made over a long period

Holy shit, you can almost see it as a wave packet propagating forward as always shown in Qm books,this is insane!
