This is a pretty interesting article here: https://techcrunch.com/2018/10/12/at-10-trillion-frames-per-second-this-camera-captures-light-in-slow-motion/?fbclid=IwAR1DJMVaiGiR5Ump3uSuPHOo-xJQK1pF7igwJol0B-V8w75Wx6Nyw8HYSpE
If only it wasn't limited to spatiotemporal datacubes. It would be awesome to see light in action elsewhere. In an environment.
Wow......... :o :o :o
I'm trying to grasp my head around it, really. Like... how? Like really how.
wondering also what can record those amount of frames? If each frame is only 1 kbyte then the drive that records have to be able to write with
9313 Gbyte per second. This means the 25 frames record is 232825 Gbyte. What kind of ssd they have?
Holy smoke. I mean . . . holy smoke.

I was wondering the same thing. Their explanation was not satisfactory. Lol I'm still trying to also grasp exactly how any cell is capturing faster than light if nothing can can "move" or "perceive" faster than light???
They explain that past streak cameras were more of a spoof, and I am wondering if that's not the case here to some degree as well, just not explained.

They don't. The article said there's no storage fast enough to store it at the same rate it's captured, so they don't. That's why they can only run it for a few femtoseconds (only 25 frames, 2500 femtoseconds were recorded in the video they showed). Presumably there's some buffer in the recording device which can hold up to 25 frames or so. Then I guess they transfer that to a drive afterwards it's finished.
