Figure 2
Left column: 2D map of the surface deformation: (a1) cryogenic mirror for Kh = 3.07, Kv = 0; (b1) cryogenic mirror for Kh = 0, Kv = 3.07; (c1) water-cooled mirror Kh = 3.07, Kv = 0; (d1) water-cooled mirror Kh = 0, Kv = 3.07. Central column: the extracted 1D profiles (a2), (b2), (c2) and (d2), respectively. Right column: the focused image with these profiles are given in (a3), (b3), (c3) and (d3), respectively. The FWHM values are: 3.85, 3.91, 8.53 and 36.34 µm, respectively (3.68 µm for the undeformed one) and the Strehl ratios are 0.99, 0.98, 0.43 and 0.11, respectively (1 for the undeformed mirror).
