Japanese researchers have unveiled the world's fastest camera which captures 4.4 trillion frames every second.
The results are up to 1,000 times faster than any camera before it.
It uses a technique called Sequentially Timed All-Optical Mapping Photography (Stamp) and is so fast that it can capture chemical reactions frame-by-frame.
The camera has been in development for three years and details of it have now been published in the journal Nature Photonics.
The researchers detailed how they successfully photographed the conduction of heat, a process which is a sixth of the speed of light.
There are a range of uses for such a camera, among them manufacturing fields that use laser cutting.
The camera could detect and allow the laser to correct cuttings as they are being performed, which could prove useful in medical fields, too.
Team member Professor Keisuke Goda, from the University of Tokyo, said the aim is to refine the camera to reduce its significant bulk. It currently measures around one square metre in size.
The pixel density is low compared to a typical camera - 450x450 - but is impressive by high-speed camera standards.
