Camera acquires data at one trillion exposures per second

Direct recording of light is impossible at a trillion frames per second, so the camera takes millions of repeated scans to recreate each image.

Such a rate is reported to be fast enough to produce a slow-motion video of a burst of light.

The team claims that the technique, dubbed femto-photography, could be used to understand ultra-fast processes.

The video produced is a composite of hundreds of thousands of videos taken over the period of an hour. Each shot is taken at a slightly different angle with a mirror and a ‘streak camera’, which is a device traditionally used to take data readings from light pulses.

According to the BBC, a laser pulse flashing briefly once every 13 billionths of a second was used to illuminate the scene for the human eye.

Andreas Velten, one of the system’s developers, calls it the ‘ultimate’ in slow motion. ‘There’s nothing in the universe that looks fast to this camera,’ he said.
