Abstract
An antenna system for receiving both RF wave and optical wave radiation via a single antenna aperture that may be moved between stowed and deployed configurations as needed. The system includes a wavefront correction system for correcting optical wavefront distortion errors caused by anomalies in the shape of the antenna aperture itself, as well as optical wavefront distortion errors caused by atmospheric perturbations. The optical components used for optical signal conditioning are supported from the antenna aperture and form a compact, unobtrusive means for separating electromagnetic and optical wave signals received by the antenna aperture.
