High-Speed Motion Pictures by Multiple-Aperture Focal-Plane Scanners

Heretofore, in all high-speed photography instantaneous time covered one complete frame, the continuity of instantaneous frames forming the time axis. This is fundamental even with image dissecting methods which reduce frame length by lateral displacement of frame elements, a trick done to shorten physically the time axis and allow the higher speeds mechanically inherent in less length of film. A new method of obtaining high-speed pictures is described whereby instantaneous time covers multiple small portions of a single frame, the total area of these small portions being sufficient to provide detail and the single frame being large enough to permit unmagnified observation. This is accomplished by multiple-aperture focal-plane scanners.
