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.
If it's possible to play this back at 24 FPS, we can shoot that 3 minute homemade porn we've always wanted!

Audio vibrations in a potato chip bag perhaps? Just saying...

You remember that "We can recover audio from a video of a potato chip bag" article right? 4.4 Trillion FPS might be overkill for that though.

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!!!
At 4.4 trillion frames a second, playing back one second of footage at 24fps would take over 5,580 years.
I guess if you're targeting a 320x240 device, that counts... otherwise, not so much.
( 450x450 is still pretty impressive at that frame rate. )
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.
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.
Still not enough for the Mythbusters.
(On a more serious note though, how on Earth do they manage to store even a few microseconds of the footage from this beast?)

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?

You can build a Forward Mass Sensor and use a magnetic cannon to launch an iridium sphere nearby...

Ah, yes. Plank time: the ultimate endpoint for pirate physicists.
420*500*16 bit pixel depth*4.4 trillion frames per second = 1,800 TB/sec. raw, obvously, because i don't know if anything can compress that fast. my ssd can do 500 MB / sec. Is that close?
Stretch those femtoseconds into hours, nice...

Will I need to update my TV to 4K to play it? Enough said.
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..
world was created 5 seconds before this post as it is.
But... uhm... you need free light to 'see'.
So how could you see the light while it is still traveling inside the glass?
1 second / 4.4 trillion * 3E8 m/s = 68 microns.
That's the distance light covers between frames. Wow.
Pity this didn't exist during the days of atmospheric nuclear testing.

You can notice the effects between two sets of dense metal spheres from gravity using your naked eye (Cavendish did so over 200 years ago), and if you're concerned with precise positioning you wouldn't need a camera, but something that just measures the position really well (e.g. an interferometer would do so to far more precision than you could easily set up with a microscope). And if you are trying to disprove general relativity's statement that gravity travels at c, you don't need cameras with trillions of frames a second, just an oscilloscope with nanosecond level resolution that you can find in a student lab these days. Or if you insist on using a camera, ICCD cameras with frame controls below 1 ns are commercially available off the shelf. More likely you will find the issue isn't the speed of recording devices, which far exceed those requirements, but the difficult in building such a setup that has a low enough noise floor.
It will take a long time to see that second!

Red light is 430 trillion hertz. So about 100 red light waves per frame.
None at all.

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..
The audio vibration in a chip bag was a nice example of high speed pictures and software using this pictures to filter out unseen movements. They work with a speed up to 6000 fps. With higher high speed we can understand / tackle hopeful vibration in constructions and machinery, as combustion engines and air planes.
Yes, it would be fairly useful for inspections in science and engineering: a way to measure precision, as well as observe rapid chemical reactions. Speaking of rapid chemical reactions, I wouldn't mind seeing a mythbuster style explosion that slow.
