Improvements in High-Speed Motion Pictures by Multiple-Aperture Focal-Plane Scanners
It is shown how, with the multiple-aperture scanning method of high-speed photography, the absolute number of entirely new position pictures of a moving object is more a function of how many grains of emulsion are uncovered in the total aperture travel than a function of the number of aperture widths uncovered. This results in many more frames per event than had been assumed heretofore. A second camera of this type is described in which two-dimensional scanning gives composite pictures with a dot structure. This is accomplished by means of a rotating disk. This camera is capable of taking high-speed pictures at the rate of at least 1,000,000 per second.
