چکیده

Space based bifocal relay mirrors are potentially an enabling/enhancing piece of any architecture making use of longrange laser propagation. Inherent in the bifocal concept is dual line of sight control. This is especially challenging in this space-based application due to spacecraft attitude control issues. This paper presents a summary ofthe research into acquisition, tracking, pointing (ATP) and control technologies relevant to a bifocal relay mirror system as well as the development of a laboratory experimental test bed to integrate the advanced optics systems onto a Three-axis spacecraft simulator. The relay geometry includes a cooperative source and either a cooperative or non-cooperative target depending on the application. The described test bed is ajoint effort with the Air Force Research Laboratory (optics) and the Naval Postgraduate School (spacecraft simulator).
