Two-stage optical detonator with shock-detonation transition

摘要

A first stage of a shock-detonation transition type two-stage optical detonator contains a pyrotechnic substance and an optical fiber, one end of which is connected to a source of laser radiation. The first stage pyrotechnic substance is separated from a pyrotechnic substance of the second stage by a metal plate, one face of which is in contact with the first stage pyrotechnic substance and whose other face is adjacent a cavity which separates it from the second stage pyrotechnic substance and whose edge portion bears against the end of a confinement member confining the second stage pyrotechnic substance.
