- Abstract
Based on a truncated ellipse Gaussian model for localized distortion in transmission-type optical antenna, the receiver power penalty due to localized wavefront deformation is researched. It is shown that the receiver power depends on distortion deepness h, radii aand b, and position d, and changes regularly with them. Localized distortion has the greatest influence on receiver power at a depth of h1.45, which does not depend on other deformation parameters. The maxima of the receiver power penalty for different distortion radii are given. To reduce the impact of localized distortion on the receiver power, the machining precision of lenses should be better than 1.45. We hope the results can be used in the design of intersatellite laser communication systems.
