rapatronic camera

Also see the photograph of an explosion using a Rapatronic camera.

The photo was shot by a rapatronic camera (a high speed camera invented by Harold Edgerton and colleagues) built by EG&G.

To overcome the speed limitation of a conventional camera's mechanical shutter, the rapatronic camera uses two polarizing filters and a Faraday cell (or in some variants a Kerr cell).

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 (100 million frames per second).
