Abstract
An example omnidirectional sensing system may include a fiber optic cable wrapped around a sphere or spheroid in no preferred direction. The wrapped fiber optic cable may make the system more receptive to acoustic disturbances and increase the fidelity of the sensor in the area of the sphere or spheroid. The system may be used, for instance, for vertical seismic profiling via a wireline technique, placement at the surface of the earth for surface seismic, and in marine applications.
