Abstract

The invention provides a copper coil-based full-tensor magnetic field gradient measurement device. The copper coil-based full-tensor magnetic field gradient measurement device comprises a gradiometer main body, a supporting base and a signal connection interface, wherein the gradiometer main body is used for measuring full-tensor magnetic field and magnetic field gradient information of each point in a space, and the full-tensor magnetic field and magnetic field gradient information comprises a response gradient value corresponding to five independent components in a full-tensor matrix and three magnetic field vector values of a central point; the supporting base is used for horizontal regulation operation which is required to be carried out during measurement of the magnetic field gradient of the space; the signal connection interface is used for transmitting weak voltage signals corresponding to the magnetic field gradient and central magnetic field intensity. According to the copper coil-based full-tensor magnetic field gradient measurement device provided by the invention, the technical defect that a traditional magnetic field gradient measurement device just can be used for measuring gradient information in a single direction of a magnetic field is solved, and the space consistency and the information integrity of magnetic field component measurement are increased.

Description

technical field [0001] The invention relates to the technical field of magnetic field gradient measurement, in particular to a full tensor magnetic field gradient measurement device based on copper coils. Background technique [0002] The so-called full tensor magnetic field gradient refers to the amount of change of the three components of the magnetic field vector along the direction of the three-dimensional space base. The measurement of the full tensor magnetic field gradient information is composed of a magnetic sensor as a basic unit through a reasonable spatial arrangement and an appropriate connection. The importance of magnetic measurement technology in scientific research, medicine and various sectors of the national economy has become increasingly prominent. According to the different requirements of various magnetic field measurements, magnetic sensors with different advantages and performances emerge in endlessly, such as fluxgate sensors, GMR, GMI, SQUID, nucl...
