Trillion FPS camera developed at MIT camera can 'watch' the movement of light


Quote by sophiecentaur View Post
I wonder whether people are getting a bit too excited about this idea of watching the progress of an EM signal through a medium. It's something that has been done for decades with RF signals. You can see and measure the change of phase (progress) along a transmission line with some very humble equipment.
Yes, of course it's good that they managed it with visible light but I think it should be viewed in context. Is there really a difference, in principle?
I wouldn't worry about that too much sophiecentaur, I am the 'odd man out' on this thread as far as being excited to witness lights movement through space lol

I wonder what physicists of the first quarter of 1900's would have given to watch this,
it seems complacent disregard is the science of our century.

I'm not knocking "informed excitement" I just like people to see things in proper context. Like I said, the same thing has been done with radio waves for ages. Using time measurements to show distance is a pretty well established technique and, without all the trimmings, that's what the demonstration is all about. (The accuracy is not that staggering in any case), you can locate features on a transmission line which are only a few mm in size.
I can tell you that a Physicist from even only ten years ago would be impressed by a lot of what 'they're' doing these days. I do agree, however, that "complacent disregard" is a failing of modern Science appreciation - ever since the Starship Enterprise technology was assumed to be a fact.

OMG! We could go out with this camera and shoot all those amazing things out there! /s

So, does each frame have dimensions of 1*xxx pixels?

I can certainly understand that. I have been reading more about this; I was waaaay off on how the 'camera' works. It seems complex the way they are getting it animated with the mirror but I am sure they are doing it the best way they can think of.

I didn't mean to gloss over your earlier statements about this, I find that quite astonishing as well.
In regards to seeing light in 'motion', to the lay person, that comes across as nothing short of incredible. I think the scientific community should take every opportunity to garner public excitement, ultimately that is good for everyone.

I nearly fell off my chair when I read that last part, ha ha!

Not a million miles from the Logie Baird approach to early TV, actually.
