World's Fastest Camera Shoots 10 Trillion Frames a Second (newatlas.com)
bbsguru shares a report from New Atlas: Slow-motion video has always been fun to watch, with the best rigs usually shooting on the scale of thousands of frames per second. But now the world's fastest camera, developed by researchers at Caltech and INRS, blows them out of the water, capturing the world at a mind-boggling 10 trillion frames per second -- fast enough to probe the nanoscale interactions between light and matter. For the new imaging technique, the team started with compressed ultrafast photography (CUP), a method that it is capable of 100 billion fps. That's nothing to scoff at by itself, but it's still not fast enough to really capture what's going on with ultrafast laser pulses, which occur on the scale of femtoseconds. A femtosecond, for reference, is one quadrillionth of a second.
So the team built on that technology by combining a femtosecond streak camera and a static camera, and running it through a data acquisition technique known as Radon transformation. This advanced system was dubbed T-CUP. For the first test, the camera proved its worth by capturing a single femtosecond pulse of laser light, recording 25 images that were each 400 femtoseconds apart. Through this process, the team could see the changes in the light pulse's shape, intensity and angle of inclination, in much slower motion than ever before.

I can prove my Canadian girlfriend is real. /s
This would be interesting to use to record the double slit experiment and find out what is really going on.
It doesn't do 4k.
A trillion frames at 1x1 is useless.
That said a super high frame rate like this is awesome.
What's the resolution though? I couldn't find it mentioned in the article.
A femtosecond, for reference, is one quadrillionth of a second.
Probably one of the world's least useful explanations.
politicians are like babies' nappies: they should both be changed regularly and for the same reasons
... the pulse of laser light said, "I've been framed."
It little behooves the best of us to comment on the rest of us.
you can't even get the angry sea bass in the shot, let alone a shark.
Hi! I make Firefox Plug-ins. Check 'em out @ https://addons.mozilla.org/en-US/firefox/addon/youtube-mp3-podcaster/
Is it real time, interleaved, or synchronous sub sampling (aka aliasing aka stroboscopic effect)?
It took only 25 frames in total. And looks like each frame is a low res pic of about 100 x 100 pixels, as far as I can tell.
sed -e 's/Chuck Norris/Rajnikant/g' joke > fact
1 ten trillionth of a second (100 fs or 0.1ps) is 29 microns at light speed.
General Relativity: Space-time tells matter where to go; Matter tells space-time what shape to be.
if we could only get LEDs to switch even 1/100th this fast. I think it's about 2ms now.
Just for those who don't mess with image analysis, it's the "Radon Transform," not a 'transformation'. The wikipedia article is long on equations and short on simple application, which is that it's a way to find critical image parameters like lines or edges.

We all know it will be porn somehow.
By 10 trillion, you mean 10^13 aka 10 billion in the rest (=non-us-english) of the world, right?!?
I want one, so I can store all 10 seconds of my daughter birthday. Can someone point me to a reseller of a 100 yotta byte SDCARD?
