摘　　要：霍尔器件可用于微位移测量,但实用时要设计复杂的磁路以保证在测量范围内为均匀梯度磁场。通常只能测1mm左右的位移,这限制了其应用范围。采用反馈随动机构带动霍尔传感器跟踪被测体的位移,从而大大扩大了位移的测量范围,且不需要在测量中保持均匀梯度磁场。Hore unit can be used to microdisplacement measurement. But it is necessary to design a complex magnetic route to ensure the even grad magnetic field within measuring field. Usually it can only measure about 1 mm displacement,which deeply restrict its application. In this paper a feedback random framework is used to drive Hore sensor to track the displacement of the measured object. This framework greately enlarges the measure range and it can also work in non-even grade magnetic field.
