Researchers in Canada have developed a camera capable of taking 156.3 trillion images per second! This technology should facilitate the observation of ultrarapid phenomena, such as the mechanics of shock waves in living cells or in matter.
Researchers are constantly trying to observe events on the scale of the infinitely small, whether in terms of size or time. When it comes to time, there is a need to create cameras capable of recording images at speeds that are almost impossible to imagine. At the end of 2018, Caltech presented a camera capable of recording 10,000 billion images per second.
The National Institute of Scientific Research (INRS) in Canada has just announced that it has created a camera 15 times faster, capable of taking 156.3 trillion images per second. They named their device SCARF, for swept-coded aperture real-time femtophotography.
A patented technology soon to be commercialized
This feat is all the more impressive as the researchers used existing components, including a CCD sensor, considerably limiting its cost. The researchers summarize the operation as “ ultra-fast all-optical scanning of a static coded aperture while recording an ultra-fast phenomenon “. This technique is detailed in an article published in the journal Nature Communications.
Such a camera will allow scientists in many fields to study phenomena that are too brief for standard cameras. SCARF managed to capture the transient absorption in a semiconductor semiconductor as well as the ultrafast demagnetization of a metal alloy. Researchers are already working with the companies Axis Photonique and Few-Cycle to produce marketable versions of this already patented technology.
