title: Spatial light coupled into a single-mode fiber by a Maksutov-Cassegrain antenna through atmospheric turbulence.
abstract: Maksutov-Cassegrains are widely used in free-space optical communication. The coupling efficiency and variance of a Maksutov-Cassegrain fiber (single-mode) system distorted by atmospheric turbulence are numerically evaluated using second-order and fourth-order moments under a Von Karman spectrum. Considering the limited cost and size of the equipment, the Maksutov-Cassegrain aperture should satisfy DA/ρS≈7 (ρSapproximates the characteristic atmospheric coherence length), and the obscuration ratio should be no more than 0.2.
