Imaging at a Trillion Frame Per Second - Ramesh Raskar
http://www.ted.com/talks/ramesh_raskar_a_camera_that_takes_one_trillion_frames_per_second.html
Although this video is extremely interesting, The part I'm most interested in occurs at about the 9:30 mark.
Ramesh Raskar says,
"But there is also something funny going on here .. the ripple are moving away from the camera towards the cap of the bottle when we know that light should be moving from cap to the camera?
Well Einstein would have loved to see this femto-photo.
It turns out that because we are recording nearly at the speed of light, there is reversal in how we observe events in the world. After a correct mathematical space-time warp, we can correct for this time distortion."
So my question is, why do we observe a reversal in the events when photographing at almost the speed of light? I may be overthinking, but I'm curious and was wondering if anybody had an explantation. Thanks in advance for any responses!
