Researchers in Japan have developed a motion picture camera that can take 4.4 trillion frames per second -- making it the fastest camera in the world. They call their technique “sequentially timed all-optical mapping photography” (or STAMP), and the resolution is an impressive 450 x 450 pixels. The work was published in Nature Photonics this week.
The current gold standard for high-speed, real-time recording utilizes a method known as the pump-probe process, Wired explains, where light is pumped at the subject and then probed for absorption. But to construct an image, it requires repetitive measurements.
Developed by a large team led by University of Tokyo researchers, STAMP uses single-shot bursts to acquire images. Its optical shutter lets it capture images consecutively in less than one-trillionth of a second. Without the need for repetitive probing, STAMP offers results that up to 1,000 times faster than existing high-speed cameras.
