Figure 4
Comparison of the experimental horizontal intensity distribution (starting at the fibre centre) across the perfect edge of Fig. 3 integrated in the vertical direction over all pixels with simulations. They are made using the procedure discussed in the text for the structural parameters of the fibre as obtained from scanning electron microscopy (SEM) images and for three different values for the spatial resolution: (a) 0 µm, (b) 0.15 µm, (c) 0.3 µm. |
