Title:
COUPLING MEASUREMENT DETECTOR
Document Type and Number:
WIPO Patent Application WO/2016/172816
Kind Code:
A1
Abstract:
A coupling measurement detector. The coupling measurement detector comprises piezoelectric ceramic crystals (1, 2, 3), a detector (4) and a corresponding power supply circuit. The three piezoelectric ceramic crystals (1, 2, 3) are respectively located at the top of the detector (4) and on two mutually perpendicular side faces. By processing data measured by the coupling measurement detector, a detector-earth coupling response corresponding to a buried point of the detector can be obtained, and then the influence of the coupling response on seismic data can be eliminated through calculation, thereby improving the fidelity, signal-to-noise ratio and resolution of ground vibration data picked up by the coupling measurement detector.
