MIT makes a 1 trillion FPS camera

The abstract from the Visualizing Photons in Motion at a Trillion Frames Per Second article:

We have built an imaging solution that allows us to visualize propagation of light. The effective exposure time of each frame is two trillionth of a second and the resultant visualization depicts the movement of light at roughly half a trillion frames per second. Direct recording of reflected or scattered light at such a frame rate with sufficient brightness is nearly impossible. We use an indirect ‘stroboscopic’ method that records millions of repeated measurements by careful scanning in time and viewpoints. Then we rearrange the data to create a ‘movie’ of a nano-second long event.

This video explains more about it and includes demos of the captured videos.
