A high-speed camera is a device used for recording fast-moving objects as a photographic image(s) onto a storage medium. After recording, the images stored on the medium can be played back in slow-motion. However, Japanese scientists now claim that they have created world’s fastest camera that can shoot a whooping 4.4 trillion frames per second.
The camera is created by the scientists of the University of Tokyo and Keio University in Japan. It is around 1,000 times faster than any other camera in the world, and is powered by a brand new technique (motion-based femtophotography) for capturing images, known as Sequentially Timed All-optical Mapping Photography (STAMP).
Chris Higgins said, “The STAMP has been proposed to improve the study of chemical reactions and heat conduction, which travels around six times slower than the speed of light. The teams, split between Keio University and the University of Tokyo, have been working on a STAMP camera for the past three years, and hope to continue to do so now that their findings have been made public.”
This camera can map the movement of an object over time into a ‘burst stream’ of photos. It can take 450 pixel square images at the rate of 4.4 trillion per second but is not compact, measuring around 3ft or one meter in length.
The Japanese scientists have described their technology about this camera in the journal Nature Photonics. At present, the scientists are working on scaling it down to prepare it for the commercial market. Scientists have mentioned that this camera will be used to examine chemical reactions and heat conduction. They also hope to see it used in several medical applications, and to study fast dynamics in photochemistry, phononics, and plasma physics.
