  • Acoustic emitters for use in marine seismic surveying
    Patent number: 6839302
    Abstract: 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 center of the emitting element, while also permitting the emitter to be spooled with the streamer.
