Using the Fermat’s principle we estimated position of image spot created by light rays passed from an off-axis point source through two different-size Mikaelian’s lenses. For the optical system with two gradient-index Mikaelian’s lenses, one of which is 2.5 times bigger than the other, an optical superresolution-image of two point sources (with a distance of 0.28l between them) with magnification of 2.1 has been obtained numerically by the FDTD-method. Also, magnification of 3.14 has been obtained by linearly tapered Mikaelian’s lens.
