Femto-Photography: Visualizing Photons in Motion at a Trillion Frames per Second
- rbdn 12y agoAm I understanding it correctly that the technique that was submitted yesterday would allow for similar frame rates even without relying on stroboscopy? https://news.ycombinator.com/item?id=8700239 https://news.ycombinator.com/item?id=8700239 Edit: I've completely missed the videos. Amazing. http://www.nature.com/nature/journal/v516/n7529/fig_tab/nature14005_SV2.html http://www.nature.com/nature/journal/v516/n7529/fig_tab/natu...
- altrego99 12y agoAm 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.
- _nedR 12y agoNot 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 https://www.youtube.com/watch?v=Y_9vd4HWlVA
