A 100,000,000 Frame per Second Camera

Shock waves close to the edge of explosive charges have been successfully photographed at rates exceeding 100,000,000 frames/sec. These ultra high framing rates are obtained with a multi-slit focal plane shutter which is transported optically across the film plane by a rotating mirror. Linear shutter speeds up to 3,000 meters/sec are easily obtained, and the resulting framing rates with the proper selection of slit widths can be varied from 10⁵ to 10⁹ frames/sec. 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.
