Am I understanding it correctly that the technique that was submitted yesterday would allow for similar frame rates even without relying on stroboscopy?

Edit: I've completely missed the videos. Amazing.

Am I wrong, or is this technique just a very advanced stroboscopy. Even though it may appear we are following the same pulse of light, that's not what is happening.

It is not one shot of light traveling, but every frame is created with a different pulse of laser captured at the right moment.

What I wonder is how did they figure out ways to capture such short exposure. That is the technological achievement making this happen.

Not sure why exactly this is news. Ramesh Raskar, the head of the MIT team doing the project did a TED talk on it 2 years ago : https://www.youtube.com/watch?v=Y_9vd4HWlVA
