The monochromatic images of unipolar sunspots in the Stokes parameters Q and U of magneto-sensitive lines display a complicated structure. This is caused by the magneto-optical effect and also connected with the 3-D structure of spot magnetic fields. In the process of numerical simulation it is possible to check the regularities of the change of the angle of inclination of magnetic lines of force with distance from spot center.
