J. Wadsworth and F. E. Stokes recently described a simple high speed camera. They formed an array of images using crossed rods of glass to form an array of small camera lenses, and each lens of this array formed a separate frame. They exposed successive frames by rotating a Nipkow disk in front of the crossed glass rods. Some years ago, I made some high speed cameras working on similar principles, but using lenticular plates as the array of camera lenses. Sequential operation could be by Nipkow disk or by control of the light sources, which could be an array of sparks, or more simply, the moving spot of a cathode ray tube. Rates of recording were in the range 105 to 106 pictures per second. The cameras are very simple and of low cost. They allow one to record long sequences of pictures. Picture quality was low but there is a reasonable prospect of improvement.
