ABSTRACT:
A trigger system for chemical actuators, e.g. of the type used for high voltage isolation, is disclosed. A light source, preferably a laser, emits a powerful, highly concentrated pulse of light energy. The pulse is conveyed by fiber optics to a chemical explosive charge, which it detonates. Because the fiber optics used are excellent electrical insulators, it is possible to locate all of the trigger system except the output end of the fiber optics at ground potential, eliminating the need for shielding the trigger system against high-voltage noise.
