Abstract
Shock waves close to the edge of explosive charges have been successfully photographed at rates exceeding 100,000,000 frames per second. These ultra‐high framing rates are obtained with a multislit focal plane shutter which is transported optically across the film plane by a rotating mirror. Linear shutter speeds up to 3000 meters per second are easily obtained, and the resulting framing rates with the proper selection of slit widths can be varied from 105 to 109 frames per second. Each individual frame is composed of a series of lines, and the degree of ``discontinuity'' across each frame is proportional to the total number of frames.Keywords
