Chaos Captured: Trillionth-of-a-Second Camera Shutter Speed.
Physicists from the University of Gothenburg have developed an ultrafast laser camera that can create videos at 12.5 billion images per second, while another camera with a trillionth-of-a-second shutter speed is able to photograph atomic activity, including "dynamic disorder." The latter camera uses neutrons to measure the position of atoms, rather than conventional photography techniques, and is referred to as variable shutter atomic pair distribution function (vsPDF). These new cameras provide more insight into the properties and reactions of materials.
