(a) Angular intensity profile Ie(dz) due to the mirror size at the optics exit (q = 0) calculated using wavefront propagation. (b) Intensity profiles at the image plane (q = 0.2 m) obtained by propagating the rays from the optics exit. Dashed line: calculated with the original ray divergences from the ray-tracing. Solid line: obtained by propagating the divergences convoluted with the wavefront propagation shown in (a). In both cases the ray positions at q = 0 are those shown in Fig. 3. |
