Abstract

A high speed photomicrography setup is described and some basic problems related are discussed, including visual field, distinguishability, time resolving power, working distance and two of most difficult ones, i.e. depth of field and luminary. An experimental optic glass acceleration bore is made, which can be used to determine the flyer velocity of slapper detonators, the shape of the exploding foil, thickness of flyer, diameter and length of the acceleration bore, and the shock initiation threshold condition of explosives. The deviation of velocity obtained from this set up is no more than +/- 2.0% when rotation speed of the rotary mirror is no less than 15 X 10⁴ r/min.
