Applications of the High-Speed Focal-Plane Shutter Camera to Explosives Research
The camera described in the paper immediately preceding in this Journal is particularly suited for the study of detonation phenomena because of its continuous coverage in time, for 216 frames, of at least some portions of the subject. The coverage feature minimizes the chance of failure to observe details of rapidly changing phenomena. The camera was intentionally designed to record the six rows of images on two film strips with the images of the three rows on each film phased one-third frame apart. In addition, the shutter apertures for each filmed group of images can be selected independently for flexibility in control of exposure. This camera has been used at framing rates up to 1.1 million frames per second to record transient phenomena in the study of the growth to detonation in explosives subjected to mechanical shocks of known amplitude. Example records of these experiments are shown and discussed.
