FIELD: seismic prospecting. SUBSTANCE: marine geophone includes seismic station, interface, testing unit 3, laser source of optical energy. Instrument sections having optical feeder with coupler, optical transducers 10, fiber-optical communication lines and photodetectors are anchored via instrument-free sections on load-carrying rope. Outputs of transducers are integrated in groups. Characteristic feature of geophone lies in insertion of unit of electron-optical and fiber-optical commutators into instrument sections. Interface includes electron-optical demultiplexers, interpolation filters, fiber-optical and electric connections between elements. Testing unit has generator of optical oscillations, electron-optical commutator, fiber-optical and electric communication lines. EFFECT: enhanced efficiency of marine geophone due to increased number of channels and testing efficiency. 1 cl, 2 dwg |
