A research team led by Lihong Wang at Caltech’s Andrew and Peggy Cherng Department of Medical Engineering have developed an ultra fast camera that is capable of taking as many as 70 trillion frames per second. In other words, it’s fast enough to see waves of light traveling and the fluorescent decay of molecules.
The camera technology is called compressed ultrafast spectral photography (CUSP) and it’s very similar in some respects to previous fast cameras he has built, such as his phase-sensitive compressed ultrafast photography (pCUP) device, which has the ability to take 1 trillion frames per second of transparent objects and phenomena. However, CUSP combines a laser that emits extremely short pulses of laser light that last just one quadrillionth of a second with optics as well as a specialized type of camera.

We envision applications in a rich variety of extremely fast phenomena, such as ultrashort light propagation, wave propagation, nuclear fusion, photon transport in clouds and biological tissues, and fluorescent decay of biomolecules, among other things,” said Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering in the Andrew and Peggy Cherng Department of Medical Engineering.
