Femtophotography vs Gigapixel cameras

Femto-photography is a new type of technique that is able to take trillions of images per second, making able to record the movement of light.

In the example they were able to record the movement of light by shooting a light bullet several times and then synchronising the diferent frames gotten so that the animation was possible.

This ability to record light could be used to “watch” around corners. The way it works its that if you shoot a bullet of lighg to a wall part of the light would bounce and spread around, if that light hits something the light would bounce back to the wall and then back to the camera. This gives you a point and a distance, repeating the process several times would give you diferent points and distances and by joining them you could get a representation of the object.

The uses that this could have are for rescuing people (for example in fires) or in medicine for endoscopes.   Here you have a link to the video if you want more information: https://www.ted.com/talks/ramesh_raskar_a_camera_that_takes_one_trillion_frames_per_second?language=en
