Title: Light in Slow Motion
Post by: Scotty on August 06, 2013, 01:59:23 am
Somebody posted this on facebook where I could see it.  It's a video showing off the capabilities of a camera that can record at one trillion frames per second.

The effects this has on observing nano-second bursts of light is... well, really awesome.

linky. (http://www.wimp.com/trillionframes/)

I won't even pretend I understand most of the tech behind it. But it seems mostly sound..

and very very pretty. Visualisation!

my understanding is it's more of an "effective" or "simulated" kind of trillion frames per second.  it's not really recording that fast, it's doing the timed pulse thing and then making a composite.  kinda like that guy that made it look like water was flowing upward by putting the stream in front of a speaker that was set just off of the frequency of the camera.  looked like the same gob of water, but was really identical ones fractions of a second later.  just, ya know, WAY faster than that.

Well of course nothing can optically record the path of a photon.  It kind of needs them to already impact the sensor to create the picture.

I suppose you could record the individual impacts of photons, however....
