Very impressive....My only beef is with the coca cola bottle....I really don't like the whether intended or unintended corporate plug in the video....Especially after the researcher made their findings open source for anyone to view and further develop....

Its showing the light slowing down because of it being refracted by the bottle (im guessing). I dont think anyone gave a shit about which bottle they used (after all, every bottle of made by some kind of company...and its not like theres a huge Coca Cola(TM) on the .gif..

Not impressive at all if you listen to him explain it.
They're misleading the audience in reality to sell the idea. The camera is NOT 1 trillion FPS. The technique allows it to appear to be 1 trillion FPS, but in reality it's just taking 1 frame shot. The camera is synced to the photon emitter. So basically there's a script that says fire light, wait 0.0000001 sec, take picture with 0.000001 exposure. Then fire light again, wait 0.0000002 sec, take picture with 0.000001 exposure. So in reality, it's not the same photon that's being captured, and not really 1 trillion FPS. It would be completely useless in the real world as well since the object has to be COMPLETELY still for this type of mapping to work.
If anything this is just a hyped-up stop motion video.

It's actually quite a smart method. No... it's not. The problem is what he's observing over the 1 trillion frames is NOT the same thing. That's like saying you've developed a way to compare different tires, but each trial you stick them on different cars. It might "look" like you have a decent result, but in reality it's not as accurate and will lead to problems later on if people try to use your method for real applications.

I should really stop posting without watching everything myself first. I hate being proven wrong
