Abstract
A horizontal acoustic vector sensor system described herein includes a housing which has a gimbal assembly therein which is attached to a sensor assembly which has multiple pairs of seismometers that arranged orthogonally to one or more neighboring pairs of seismometers, along an approximately horizontal axis. The gimbal assembly with sensor assembly are enclosed within the housing by an endcap which includes an electronics assembly. The multiple pairs of seismometers are wired to the electronics assembly through a slip-ring which allows for movement of the gimbal assembly without entangling the wires. The horizontal acoustic vector sensor system further includes at least one omni-directional hydrophone integrated into the endcap.
Claims19
A horizontal acoustic vector sensor system comprising:
- a housing;
- a gimbal assembly within the housing including a sensor assembly and an outer gimbal, the sensor assembly including multiple pairs of seismometers, wherein each pair of seismometers is arranged orthogonally to one or more neighboring pairs of seismometers, along an approximately horizontal axis;
- an endcap for enclosing the gimbal assembly within the housing;
- and
- at least one omni-directional hydrophone integrated into the endcap on a side of the endcap that is opposite the gimbal assembly.
A horizontal acoustic vector sensor system comprising:
- a dome-shaped housing having a single accessible end;
- a gimbal mount contained within the dome-shaped housing;
- a sensor assembly mounted within the gimbal mount, wherein the sensor assembly includes three pairs of seismometers, wherein each pair of seismometers is arranged orthogonally to one or more neighboring pairs of seismometers, along an approximately horizontal axis;
- an endcap for closing the single accessible end of the dome-shaped housing and enclosing the gimbal mount and sensor assembly within the housing;
- at least one omni-directional hydrophone integrated into the endcap on a side of the endcap that is opposite the gimbal mount;
- and
- an electronics assembly integrated within the endcap, wherein the electronics assembly is physically wired to the sensor assembly via a slip-ring.
