Fantastic video! Its so amazing to see how light really travels!

[Merci Alizée]

One more development which would be put for both use and misuse.

Thanks MA. Very nice stuff!

Bringing Einstein’s Special Theory of Relativity into it with references to “space and time warp corrections” is really silly though. There is nothing surprising about the fact that “ripples” on the table move away from the observer (the camera). It is the reflections that are moving away from the observer, not light waves per say. Light detected by the camera is always moving towards it, otherwise there would be no light to be captured. The phenomenon is basically the same as if one captures sequential frames of a reflection (off any surface) which is moving away from the camera. The sequence played in a movie will show the reflection moving away from the observer, but during each exposure, the light waves from the reflection captured by the camera were moving towards it.

Nevertheless, this was a very impressive piece of technological work.

Interesting. And imagine if we are really able to see inside the human body someday without having to subjecting the body to harmful radiation (as in CT scan). Many lives would be saved each year.
