Figure 3
(a) Open circles represent the measured intensity distribution in the best image plane for the vertical configuration. The line is the related simulation for (see main text for symbol explanation) m0 = 2.0; Δm = 0; = 1.0; R = 2.8 µm; = 0; = 0 and = 0.95. The intensities are given in arbitrary units and are made to coincide in the maximum. (b) Same as in (a) but for the horizontal configuration. The simulation (line) is for the same parameters except = 0.55. |
