Abstract
The detonating device for a secondary explosive charge includes energy reservoir means and exploding foil igniter means coupled to the energy reservoir means by an optical commutator functioning in photo-conduction mode. The device may be extended to any number of separate detonation channels, and each detonation channel may be supplied with optical pulse beams generated by a single laser source or by separate, dedicated laser sources. The optical pulse beams are guided via optical fibers that may vary in length in accordance with preprogrammed detonation timing sequences. The invention finds particular application in the field of high safety detonation systems.
