The Design Of Full Tensor Magnetic Gradient Probe

With the development of science and technology, aeromagnetic superconductingmagnetic field gradient sensor gradually increased in sensitivity, becoming anultra-precision magnetic sensor. However, our study of the magnetic field sensor isstill in its infancy.To further improve the detection accuracy of the magnetic field gradient sensors,to obtain more accurate data processing result, Firstly, structure the detection model,the structural design of the sensor coil, the structure can be directly used to detect themagnetic field gradient values, combined with three-dimensional space knowledge ofgeometry, for the placement of the magnetic field gradient sensor coil design, finallythe product sensor gradient and the corresponding angle,then with sensor projectedlength do providers, seeking magnetic field gradient tensor. Calculated two data tables,can easily and quickly find the gradient tensor look-up table, reducing the number ofcomplex calculations. After analysis of five and three pyramid probe structure,deduced the structure formula of the magnetic field gradient tensor, this same formulato calculate five independent tensor components of the3*3matrix.Finally, simulation experiment, get the simulation model of the probe, comparedto vector length of the original coordinates of the points and the vector length afterprojection point, verify the accuracy that seeking magnetic gradient tensor withProjection Method. Through simulated get when six probe model angle changeoccurs, correspondence between curves of X, Y, Z each axis angle change and changesin the coordinates of the points vector length.
