Title (EN) ACOUSTIC EMITTERS FOR USE IN MARINE SEISMIC SURVEYING
(FR) EMETTEURS ACOUSTIQUES DESTINES A ETRE EMPLOYES DANS LA SURVEILLANCE SISMIQUE MARINE
Abstract: front page image
(EN)An acoustic emitter for coupling in series in a marine seismic streamer is provided with an annular housing and an annular piezoelectric emitting element positioned coaxially within the housing. This form of construction permits the electrical or electro-optical transmission line which normally runs along the axis of the streamer to pass through the centre of the emitting element, while also permitting the emitter to be spooled with the streamer.
(FR)L'invention concerne un émetteur acoustique destiné à être couplé en série dans une flûte sismique marine, ledit émetteur comportant un boîtier annulaire et un élément émetteur piézoélectrique annulaire logé coaxialement dans le boîtier. Ce type de construction permet de faire passer la ligne de transmission électrique ou optoélectrique, s'étendant habituellement le long de l'axe de la flûte sismique, au centre de l'élément émetteur, l'émetteur pouvant par conséquent être bobiné avec la flûte sismique.
