The team of Professor Jinyang Liang, specialist in ultrafast imagery at the National Institute of Scientific Research (INRS), in collaboration with an international team of researchers, has developed a camera, the fastest in the world, capable of to image ultraviolet (UV) photons in real time.

Imagine being able to snap a picture of extremely fast events on the order of a picosecond (11 zeros after the decimal point!).
Compressed ultrafast photography (CUP) captures the entire process in real time and unparalleled resolution with just one click. The spatial and temporal information is first compressed into an image and then, using a reconstruction algorithm, it is converted into a video.
Jinyang Liang, who led the study, said:
“Many phenomena that occur on very short time scales also take place on a very small spatial scale. To see them, you need to sense shorter wavelengths. Doing this in the UV or even X-ray ranges is a remarkable step toward this goal.”
