The capacity to integrate RF and free space optical hybrid communications now feasible
given advances in adaptive optics and optical automated gain control. The ORCA program is
developing on operationally capable of highly reliable hybrid communications. This paper
provides an overview of the ORCA systems and discusses some of the key developments in
making the systems a reality.© (2008) COPYRIGHT SPIE--The International Society for Optical Engineering. Downloading of the abstract is permitted for personal use only.
