Title:
OMNI-DIRECTIONAL VECTOR DIVERGENCE SEISMIC WAVE DETECTOR
Document Type and Number:
WIPO Patent Application WO/2017/071437
Kind Code:
A1
Abstract:
The present invention discloses an omni-directional vector divergence seismic wave detector, comprising: four detectors and a support structure, the support structure being used for supporting the four detectors, such that the bottoms of the four detectors are respectively positioned on a regular triangular surface of a regular tetrahedron, the intersection point of the working axis of each detector and the corresponding regular triangular surface being located at the centre of the regular triangular surface. According to the formula for Gauss divergence in field theory, the present invention is designed with a specific spatial motion vector detection structure, and thus implements information detection of properties such as the frequency, amplitude, phase and vibration direction of the seismic wave field, in particular the degree of divergence of the wave power field, forming a new omni-directional vector divergence seismic wave detection technology.
