| 英文摘要 | An anamorphic system and method having first and second reflective anamorphic surfaces producing different magnifications in orthogonal directions in a collimated beam of radiation incident on the first anamorphic surface. The anamorphic surfaces have parabolic cross-sections in the two orthogonal directions. The parabolic cross-sections have base radii of curvatures and the magnifications in the first and second directions are determined by the ratio of the base radii of curvatures in the first and second directions. |
