About this title

Synopsis

Explore how spark photography reveals high-speed events in ballistics, turning fleeting moments into clear silhouettes for study.

This classic work explains how ultra-short electric sparks capture moving objects without lenses, and how timing and spark duration affect the clarity of the record. It also details the equipment setup, from high-voltage energy storage to precise triggering systems, and shows how these ideas are applied to problems in interior and exterior ballistics.

The text surveys the methods for photographing projectiles at very high speeds, analyzes the acceleration of bullets after leaving the muzzle, and examines how propellant gases and surrounding media influence the observed phenomena. Readers will see practical demonstrations of speed determination, gas leakage, and sound-wave interactions, along with discussions of wake patterns and the effects of different media on shock fronts and waves.

How instantaneous light is generated and synchronized for sharp, ghost-free images
How to measure projectile speed and track acceleration just after discharge
How gas flow, leaks, and surrounding media alter observed effects
How medium changes affect sound waves and the behavior of projectiles in flight

Ideal for readers of historical scientific methods and those curious about early techniques for visualizing high-speed events in ballistics.
