【Abstract】 Applying matrix optics to paraxial rays, which travel through different optical elements illuminated with high-power Gaussian beams, the positions of ghost images affected by Kerr-effect-induced nonlinear refractive index of the illuminated optics are studied. Calculations are made on the position shifts of several low-order ghost images arising from spacious reflections at surfaces defining an isolated convexo-convex lens, concavo-concave lens, and optics forming the so-called 4F system. The variation rules of the position shifts are quantitatively shown as functions of the beam waist radius and the beam peak intensities.更多还原
