Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The rapatronic camera (a contraction of Rapid Action Electronic) is a high-speed camera capable of recording a still image with an exposure time as brief as 10 nanoseconds (billionths of a second). The camera was developed by Harold Edgerton in the 1940s and was first used to photograph the rapidly-changing matter in nuclear explosions within milliseconds of ignition. To overcome the speed limitation of a conventional camera's mechanical shutter, the rapatronic camera uses two polarizing filters and a Kerr cell. The two filters are mounted with their polarization angles at 90° to each other, to block all incoming light.
