A high speed photography technique is described which combines a very bright light source, optical fibers, and a rotating mirror camera to obtain sub-microsecond definition of high speed events. Applications described here include the measurement of the onset of detonation in an explosive, the measurement of projectile velocity, and the evaluation of planarity in a shock front. The fiber optics assemblies may also be used as image dissection devices, converting macro pictures to slit images. The previous work by W. Hertz is reviewed and modifications to this technique are described.
