The new camera is called a compressed ultra-fast photography or CUP camera. It uses compressed sensing, which allows the camera to make better pictures from gathering less data. The camera works at up to 100 billion frames a second, compared to the millions-of-frames-per-second speed of previous ultra-fast cameras. This isn't the fastest ultra-fast camera ever invented--in 2011, researchers built a one trillion frames-per-second camera)--but that one only works on repeating phenomena, because it needs to take several pictures of similar events and then piece together what it sees. The CUP camera works on fleeting, non-repeating events.
