abstract

Imaging through volume turbulence gives rise to anisoplanatism (space-variant blur). The effects of volume turbulence on imaging are often modeled through the use of a sequence of phase screens distributed along the optical path. Wallner recently derived a prescription for the optimal functional form and location of multiple phase screens for use in simulating the effects of volume turbulence in infinite-range imaging geometries. We generalized Wallner's method to accommodate the finite range case and to have a more optimal functional form for the phase screens. These methods can also be used for designing a multi-conjugate AO system. Examples of optimal solutions are given for horizontal-path finite-range imaging cases.
