Trillion-frame-per-second Camera Captures Propagat

gentryx writes "MIT has published a story on how the fastest camera on earth can capture a trillion frames per second, making it possible to trace for instance how a laser pulse moves through a bootle (more footage here). Ramesh Raskar, one of its inventors, also calls it the world's slowest camera, since the actual capture of the image sequences takes hours. The reason for this is that the camera doesn't take 2d pictures, but just 1d streaks — at a very high framerate. To obtain a 2d movie, the camera has to film the same experiment over and over again, tilted at different angles. However, in its intended use-case the camera only has to take 1d frames anyway: it is meant to study light absorption of molecules."
