Camera system catches speed of light
By Doug Gross, CNN
CAMBRIDGE – A trillion exposures per second sounds amazingly fast. But that capacity is what you need in a camera if you’re going to capture images of the speed of light.
A team of MIT researchers say they’ve created a revolutionary camera system that can, literally, render the speed of light in slow motion.
“There’s nothing in the universe that looks fast to this camera,” said Andreas Velten, a post-doctoral researcher who called the system the “ultimate” version of slow motion.
The imaging system relies on creative use of a streak camera – a tool used for measuring light’s intensity. The team set up a series of 500 sensors, each programmed to go off one-trillionth of a second after the last.
The result, shown in a video on MIT’s site, makes a laser-generated bolt of light appear as if it were moving slowly through a clear soda bottle.
