Abstract
The free space optical communication systems should utilize optical antennas with beam tracking mechanisms. However, the narrow field of view and optical aberration of antennas degrade the tracking performance of the system. In order to overcome the problems, we investigate the wide field of view optical antenna technology. The optical antenna consists of fisheye lens, compensating lens and a catadioptric telescope with off-axis aspheric surface mirrors. The structures and performances of the optical device elements are numerically analyzed so that their designs can make positive contribution in enlarging the field of view and reducing the optical aberration. The final optical antenna design is presented, along with the evaluation of optical performance and tracking characteristics. The proposed optical antenna could not only provide a wide field of view with approximately 60 degree and expand the range for tracking mechanism, but also mitigate the optical aberration and improve tracking accuracy of free space optical communication systems in turbulent atmosphere.
