Transfer function for a beam energy of 200 kV, CS3 = 0.5 mm, condenser angle 0.1 mrad, defocus spread 50 Å, and defocus of (a) 434 Å, (b) 1091 Å. The solid line is and the dashed line is . (c) The effective transfer function for the exit wave reconstructed from the defocus series of five images in Fig. 12 using the NLIP approximation. |
