World's Fastest Camera Shoots 10 Trillion Frames a Second (newatlas.com) 62
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.

This would be interesting to use to record the double slit experiment and find out what is really going on.

Depends on what we mean by reality!
In the classical sense, reality is independent of observation. Not so in the realm of quantum mechanics, where observation is not possible without interaction which in turn effects the state being observed/measured.

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.

This isn't definitive, but one of their previous papers shows images at 150 x 150.

I'm guessing that since they are looking at frickin lasers, they aren't too concerned about getting much better than that.

Google "6 inches in attoparsecs" and it replies "4.93895". In other words, not a flattering unit for the male anatomy, but useful if you want a close approximate to a decimal foot.

Hmm, had I been awake, I would have described that as cosmology's decimal inch.

The UK definition is 10 ^26
I think you mean 10^24. Also, I'd rather call it the European definition (or more precisely the long scale), because I've seen both definitions used in the UK, probably via American influence.
The European/long scale is easier to remember, because the number of zeros is 6 times the number from the name. Here, quad = 4 so we get 24. In the US scale, the logic goes as 3 + 3*quad = 15.

Synchronous, if I understand correctly. Physically, they capture two 2D images simultaneously - one "straight" and one "sheared" - then use them to digitally reconstruct a 3D spatio-temporal image.
It's a bit like how your eyes, observing the same scene from two different angles, let you construct a three-dimensional mental image - but in this case, the third dimension is time.

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.
