FIELD: measurement technology, monitoring seismic vibrations of sea floor. SUBSTANCE: inertial mass in the form of ball is positioned inside springy substrate in the form of hollow sphere. Signal fiber coil of interferometer is tension-wound on outer surface of ball substrate. Reference fiber coil of interferometer is wound on float of neutral or positive buoyancy coming in the form of sphere placed in sea environment close to substrate. Anchor is attached to lower part of springy substrate. EFFECT: potential of isotropic recording of seismic vibrations of sea floor along all directions. 4 cl, 2 dwg |
