The Camera That Can Slow Down Light

The Camera That Can Slow Down Light

Created by MIT Media Lab's Camera Culture group, this imaging system performs "Femto Photography." With an exposure time of about two trillionths of a second, it can indirectly depict how light travels in a single nanosecond, stretching the progress into a "movie" that is several seconds long. The movie is an indirect way of capturing the light because it actually consists of millions of separate recordings, each of which shows the light in a position that's slightly farther along than the last.
