Abstract

The present invention relates to ordnance ignition systems and methods having significantly improved safety and reliability characteristics. In a preferred embodiment, laser energy is used to fire both deflagrating initiators and deflagration-to-detonation devices via fiber optic cable assemblies (FOCA). Relative to known explosive transfer assemblies, FOCAs are lighter, more reliable, less costly, and can be easily and thoroughly tested nondestructively. Although the laser initiated devices (LID) contain moderately sensitive pyrotechnics, their electrical isolation renders them immune from inadvertent initiation by electromagnetic and abnormal optical environments.
