The best phone cameras can record slow motion with under 1,000 frames per second. Commercial rigs generally shoot with several thousand. But that all absolutely pales in comparison to the new record holder for the world’s fastest camera, boasting a mind-boggling rate of 70 trillion frames per second. That’s fast enough to capture light waves in movement.

Developed at Caltech, the technology is called compressed ultrafast spectral photography (CUSP). As you might expect from the incredible frame rate, it doesn’t function like any ordinary camera. It uses extremely short pulses of laser light, each one lasting just one femtosecond. For reference, that’s one quadrillionth of a second.

A system of optics splits up these pulses into even shorter flashes. Each of these pulses then strikes a specialized sensor in the camera, producing an image. And that happens 70 trillion times a second.

The CUSP system is based on an earlier technology developed by lead author of the study Lihong Wang. The original version, known as compressed ultrafast photography (CUP), managed a top speed of 100 billion frames per second back in 2014. By 2018 the team had managed to shoot at 10 trillion frames per second, using an advanced version of the tech called T-CUP.
