Photographers normally use a flash to freeze quick-moving subjects, but now a team at MIT have created a camera so fast that it can video a flash of light itself.
The camera records one trillion exposures per second, enough to capture a pulse of light passing through a bottle in slow-motion. Its narrow-slit aperture can only capture a thin line of each scene in one go, but combining the camera with a revolving mirror system allows it to record multiple lines and build up a full picture.
