Abstract
The invention discloses an omnidirectional vector geophone, comprising: eight wave detectors and support structures thereof, the support structures are used for supporting the eight wave detectors such that bottom surfaces of each two wave detectors are on one of regular triangle surfaces of a regular tetrahedron, crossing points of working shafts of the two wave detectors that are on the same regular triangle surface that cross with the regular triangle surface are both on an angular bisector of an angle of the regular triangle surface and are symmetric with respect to the center of the regular triangle surface. In the invention, based on divergence and curl equations of field theory, a particular spatial motion full-vector detection structure is designed to realize detection of full information including frequency, amplitude, phase, vibration direction of the seismic wave field, especially divergence and curl of a wave force field, to form a completely new omnidirectional vector geophone structure.
