Figure 5
Variation of the Strehl ratio at E = 230.888 eV as a function of the deformation radius of curvature in M1 for (a) convex curvature (bump) and (b) concave curvature (anti-bump). Deformation is compensated with the corrective profiles in M3 expressed as a function of the AXO basis for two cases: crop the profile to the AXO dimension (case A), and extrapolate the profile outside the AXO mirror (case B). |
