Super fast camera can film light at 1 trillion frames per second
- gus_massa 11y agoAn important detail is that it's not a camera in the normal sense. It's more like a automatic stop motion device. To "film" the 1 trillion frames in 1 second it repeats the experiment 1 trillion times. Each time the interval between the flash and the capture is slightly bigger, so you get 1 trillion different frames that can use for a movie. On particular, you can only use this with static objects. If you put a fish inside the bottle, the fish would be in different random places in each frame and the movie will be horrible.

- cLeEOGPw 11y agoThe camera is not fast in capturing so many frames per second sense. It is fast in capturing extremely short period of time sense. Many packets of photons are sent and many short movies are filmed (with 1000 frames per second or so), and later software joins all the movies together, calculates which frame belongs where and we get this result.
