Synchronous Recording of High-Speed Flying Object

Synchronous recording of plastic pellet (speed approx. 50 m/s) penetrating a plastic film viewed from different recording directions. Synchronous recording of situation before and after penetration achieves multi-directional phenomena analysis that is unavailable when recording from a single direction. (Recording speed: 125,000 fps)
