Methods for modeling and calibrating 3D probes of the magnetic field on splitting Holly structures
Main Article Content
Abstract
The work proposes a method of modeling and calibration intended for defining coefficients of field characteristics of 3D magnetic sensors based on splitted Hall structures. A splitted Hall structure allows to locate the sensor sensitive region in its corner, so having constructed a 3D sensor appropriately one can achieve high spatial resolution. The coefficients of field characteristics can be found using calculus of approximation and triples of a 3D sensor’s output signals obtained during its arbitrary rotation in a uniform magnetic f
