STORY: SOUNDBITE (English) ELIAS KRISTENSSON, LUND UNIVERSITY, CO-CREATOR OF FASTEST CAMERA, SAYING: "The camera we're using is extremely slow. But we have figured out a way so that we can record several images in one image, so we can acquire an entire video sequence in one shot." SOUNDBITE (English) ANDREAS EHN, LUND UNIVERSITY, CO-CREATOR OF FASTEST CAMERA, SAYING: "In a regular camera, in a regular video camera or a high speed camera, you take one image, you store it, and after you store it you take another one and you store that one and eventually you have stored enough images that will make a movie. Here we don't do that. We take all four images in one photograph. And then we divide them afterwards in a computer and arrange them in a way in a movie." SOUNDBITE (English) ELIAS KRISTENSSON, LUND UNIVERSITY, CO-CREATOR OF FASTEST CAMERA, SAYING: "We regard this mostly as a tool for scientists, of course, that want to be able to study ultrafast phenomena in their laboratories. And it's, of course, we don't think that it will be used by ordinary people in their homes.... "This is the heart of the concept. This is a glass plate and imprinted into this glass plate there's a periodic pattern of stripes and we tag our laser pulses with these kind of optical devices to be able to then afterwards recognise different sequences in the video... "We've not actually reached the limit of how fast you can record things. So with our laser we could achieve a frame rate of around 5 trillion frames per second. Now if you have a fast laser system you can actually beat this record, and many people, many facilities have faster lasers you have attosecond lasers. That means they could actually reach frame rates about a thousand times faster."
