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.
