1949 FOCAL-PLANE SCANNERS 461 moving at constant rates will lean over in their own planes, very much like the numbers shown in Figs. 7 and 8. The numbers on the fastest moving belt will, of course, lean more than those on the slower moving belt. The numbers on the belts that are being accelerated and decelerated do very interesting things. Rotating the grid in one direction will make the numbers lean, of course, but the planes of the numbers also tilt, the accelerated numbers tilting their tops toward the screen plane and the decelerated numbers tilting their bottoms toward the screen plane. Fig. 9 — Multiple images recorded without the capping shutter. Without painstaking measurement of the position of fuzzy unsteady pictures, good indications are thus given as to the sign and magnitude of the function photographed and its first and second time derivatives. Further study should be given to the acuity of stereo interpretation of data, and a great deal of work should be put on the use of multiplesequence photography of the type shown in Fig. 9. It is hoped to describe in a later paper these subjects as well as a camera with a two-dimensional scanning system capable of taking at least a thousand pictures at a rate of at least a million pictures per second.
