PHOTOPYROTECHNICAL INITIATION DEVICE AND DETONATION CHAIN USING THIS DEVICE

摘要

A pyrotechnic charge 22, 24 can be initiated by a laser beam 38 is mounted in a solid body 18. The beam is transported by an optical fiber 12 which penetrates in a connector 48 mounted on the body 18. The beam which is divergent at the outlet of the fiber 12 is made parallel by a first lens 50. A second lens 54, rise in the body 18, the beam to converge and co-operates with a transparent fence 40 in order to focus the beam at a given point. The means of fluid-tightness are provided between the transparent fence 40 and the body 18 of the device thus ensuring the confinement of the charge 22, 24. / p & & p & application to the explosive devices powered by a laser source.
