World's Fastest Camera Captures 4.4 Trillion Frames Per Second
Diggester writes Japanese researchers have recently designed a motion picture camera which is capable of capturing 4.4 trillion frames per second, making it the fastest camera in the world. The technique that allows for such speed is called STAMP (sequentially timed all-optical mapping photography). The research paper, published in the journal Nature Photonics has the full details.

Trolling is a art,
but does it go to 11 ?

This technology sounds totally cool. I'd like to see them use it to take pictures of somebody viewing the shitty Slashdot Beta site. They could capture the user's extreme boredom as this user waits for the shitty Beta site's page and all its shitty JavaScript and CSS crap to initially load. Then they could capture the trillionth of a second when the person notices that it's the shitty Beta site rather than the Classic site, and the person's anger starts to grow. The photos would progressively show the anger turning into madness, and then finally utter and complete disappointment and despair once the shitty Beta site has finally loaded. The photos could also capture the formation and flow of the very first of many teardrops to cascade down this poor victim's cheeks as the user struggles in vain to read the stories' small text with poor contrast. These trillions upon trillions of frames of total anguish could be examined in excruciating detail, so the awful nature of the Slashdot Beta site could be truly comprehended.
That's if you want to watch it in realtime. Things, such as bullet dynamics, railguns, physics labs, so on so forth, would have great use for such a camera.
FOR SCIENCE!!!
Picosecond resolution... ....only 30 or so more zeros until we hit one frame per plank time.
First FTA: There's a mention of a previous camera...
"Back in 2011, researchers from MIT created a high-speed camera that captured light passing through an empty bottle in slow motion by acquiring visual data at one trillion frames a second – to the STAMP cam, more than four times faster than this, even the speed of light could be as stimulating as watching paint dry."
That's misleading. The camera in 2011 didn't do amazingly high FPS capture. What it did have was very short capture with precise timing. That video of a laser moving through a bottle was actually thousands of successive laser shots. More like stop-motion than video.
Now this camera I see fewer details on. I do see that one thing it seems to do is to divide a laser with a prism and use the separation to make virtual frames by using different receptors.
Let me make an analogy. If you took a normal RGB color sensor from a camera, and exposed it, and during that exposure you fired a red flash, then a green flash than a blue flash one after the other. Take your resulting picture and break it into three by color and you have 3 "frames". They appear to be doing this with a large number of wavelengths.
Finally, a cable network with no reruns.
It seems to me a camera ilke would be useful for viewing things that happen very quickly, for instance, particle collisions in an atom smasher.

Exactly. But until they capture and show something better than this I say Meh.
I mean, the speed of light is 299,792,458,000 Millimeters per second. Maybe I miscalculated something (I always get confused with the way the US names its powers of 10), but doesn't that mean that in 15 frames of this movie, light only moves for about a millimeter? Someone with more background in physics may shed some light onto this (no pun intended), but when you're dealing with stuff SO fast that it approaches the speed of light, isn't measuring and recording subject to the problem that you cannot transport information (and thus also the result of your experiment to the observing camera) faster than said speed of light?
We used to have a Bill of Rights. Now, with the rights gone, all we have left is the bill.
(On a more serious note though, how on Earth do they manage to store even a few microseconds of the footage from this beast?)
They don't. From the full paper:
In our proof-of-principle demonstration, the total number of frames was limited to six due to our simple embodiment of the SMD (Supplementary Figs 3 and 4), but can be increased up to 100 by increasing the number of periscopes in the periscope array of the SMD or by using a more complex design (see Methods and Supplementary Section ‘Improvements in STAMP's specifications’)
You can't just record an indefinite length movie with this thing, you basically need to alter the hardware to record longer segments (since it has different physical elements detect different frames of the signal).

audio? you'd need 44 trillion samples/s for capturing audio?
I suppose you could sell it to audiophiles for inspecting their equipment though still..

There's a very simple test of the general relativity law about the speed of gravity - and it has already failed it spectacularly.. Put simply if gravity moved at the speed of light then the gravitational fields of black holes should collapse in on themselves leaving them externally massless. If you take the simplest classical model of black hole with a central singularity then the inner event horizons require higher and higher escape velocities towards the centre and gravity must jump over the whole lot to escape from the edge. This requires A - an absolute frame for space ruling out a curved space time, and B sets a minimum speed for gravity which is close to FTL Simultaneous - ie nearly 'infinitely' fast.
This model is not accepted in modern physics - but it is powerful and simple (orders of magnitude simpler than most others), and has no obvious point where it fails. (KISS - Keep It Simple Stupid - Occam's Razor) The real problem of course is that physicists are very stubborn and don't like their favoured solutions being contradicted - even in the face of direct evidence...
Below the speed of light Special Relativity is one of the most accurate theories in physics - above the speed of light..
