Abstract
We describe an analytic model for the point spread function in astronomical imaging through atmospheric turbulence with modal adaptive correction. The model includes the effects of seeing quality, degree of modal correction, angular anisoplanaticism, and wavefront sensor noise. Anisoplanatic effects are contrasted for cases where the correcting mirror is conjugate with the telescope pupil and with the atmospheric turbulence. The properties of the point spread function are described in terms of its shape, Strehl ratio, and included energy widths.
