Abstract (en)

The two-stage optical detonator has a first stage (1) containing a pyrotechnic compound (2) and linked via an optical fibre (3) to a laser radiation source. The first and second stage pyrotechnic compounds are separated by a metal plate (7) which has one face in contact with the first stage pyrotechnic compound and the other adjacent to a cavity (8) separating it from the second stage pyrotechnic compound (5). The periphery of the metal plate is in contact with the end (9a) of the second stage compound container (9).

Abstract (fr)

Le premier étage (1) du détonateur comprend une composition pyrotechnique (2) et une fibre optique (3) dont une extrémité est raccordée à une source de rayonnement laser. Les moyens qui séparent la composition pyrotechnique (2) du premier étage (1) de celle du second étage (5) comprennent une plaquette métallique (7) dont une face est en contact avec la composition pyrotechnique (2) du premier étage (1) et dont l'autre face est adjacente à une cavité (8) qui la sépare de la composition pyrotechnique (6) du second étage (5) et est en appui par sa périphérie contre l'extrémité (9a) d'un élément de confinement (9) de la composition pyrotechnique du second étage (5). <IMAGE>
