Scientists have developed a super-fast camera that can film at a rate of five trillion images per second, fast enough to visualise the movement of light.
Currently, high-speed cameras capture images one by one in a sequence, filming 100,000 images per second. The new technology, called Frequency Recognition Algorithm for Multiple Exposures (FRAME), is based on an innovative algorithm. It captures several coded images in one picture and sorts them into a video sequence afterwards.
The camera will be able to capture rapid processes in chemistry, physics, biology and biomedicine, that so far have not been caught on film.
A research group at Lund University in Sweden successfully filmed how light — a collection of photons — travels a distance corresponding to the thickness of a paper.
