458 TUTTLE November each one-thousandth-inch movement of the grid we are entitled to have a new position picture of the object, it is obvious that we shall not have to move the grid very fast to achieve high-speed motion pictures. One inch per second will give the equivalent of one thousand pictures per second. In spite of the fact that our individual picture size is 10 X 12 inches, we need to move the grid only 0.030 inch to take thirty pictures, instead of the thirty feet we would have to move the film to take thirty one-foot high pictures in more orthodox ways. Because the film plate is stationary, the image steadiness, of course, is excellent. Fig. 6 — 16-mm frame showing high-speed numbers. A 4 X 5-inch camera was built to try out the high-speed use of the moving-grid system. The grid in this camera was spring driven and moved a total of 0.090 inch. During the first one third of this motion, no exposure is produced because of the action of a multipleaperture capping shutter. Exposure occurs for the next 0.030 inch, and the last third of the motion is used to decelerate the mechanism with the slits capped. Fig. 5 shows the performance of the grid and capping-shutter system. Picture speeds of 16,000 per second have been achieved with the particular spring drive used. A motion picture film has been made from the grid playback of
