Abstract

We propose an inverse-function-based nonlinear compensation method to deal with the saturation characteristic in the magnetism gathering OCT. A polynomial expression model of the magnetic saturation characteristic is constructed via the direct method

and a computation method for polynomial coefficient is deduced by using the matrix calculation method. The existing parameters of the magnetism gathering OCT measured in the laboratory are used to obtain the nonlinear compensation model for adjusting the output of the magnetism gathering OCT. Experimental results verify the effectiveness

precision and applicability of this compensation method.
