Anamorphic imaging with three conic mirrors

Anamorphic imaging with three mirrors: a survey

“…By considering a Taylor expansion of the imaging properties about the base ray, individual construction parameters can be constrained to ensure a given set of low-order image properties. For example, four construction parameters can be constrained from the four first-order imaging properties of the plane symmetric system [8]. In a centered system, this process is analogous to placing a "solve" on the final curvature in a lens to ensure that the axial ray height is zero at the image, or that the system has a desired focal length.…”

“…S 11, S22, etc.). The methods for determining the exact analytic constraint equations are described elsewhere [1] - [8].…”

“…The studies have included systems with two conic mirrors [3], and spherical mirror systems with two, three and four mirrors [4][5][6][7]. More recently in 2002, nonanamorphic systems composed of three conic mirrors were reported [8]. In this paper, we consider plane-symmetric systems of three mirrors, but release the constraint that the mirrors be conic, and we allow for anamorphism (i.e.…”
