HE WORLD’S FASTEST CAMERA CAN “FREEZE TIME,” SHOW BEAMS OF LIGHT IN SLO-MO

Single-shot real-time femtosecond imaging of temporal focusing

When you push the button on a laser pointer, its entire beam seems to appear instantaneously. In reality,though, the photons shoot out like water from a hose, just at a speed too fast to see.

Too fast for the human eye to see, anyways.

Researchers at Caltech and the University of Quebec have invented what is now the world’s fastest camera, and it takes a mind-boggling 10 trillion shots per second —enough to record footage of a pulse of light as it travels through space.

The extraordinary camera, which the researchers describe in a paper published Monday in the journal Light: Science & Applications, builds on a technology called compressed ultra fast photography (CUP).

CUP can lock down an impressive 100 billion frames per second, but by simultaneously recording a static image and performing some tricky math, the researchers were able to reconstruct 10 trillion frames.

They call the new technique T-CUP, and while they don’t say what the “T” stands for, our money is on “trillion.”
