Summary The objective of this project is to develop technologies in adaptive optics for flexible mirror surface control and beam control to minimize aberration in images and develop technologies in advance control to minimize the impact of mirror structural flexibility on pointing control and settling time during slew maneuvers. The emphasis in this project will be on adaptive optics. This is a joint AFIT/NPS project. The work to be performed by NPS is given in this proposal. During the Phase I, the focus will be to set up a test bed and demonstrate the correction of mirror surface and image aberration by using adaptive optics. In Phase II, the focus will on developing and testing various wave front sensors for monitoring the surface of the primary mirror and adjusting it. The deformable mirror in Phase I test bed will be replaced by a telescope with a mirror with active surface control. In Phase III, the main objective is to integrate adaptive optics techniques developed at NPS and at AFIT into NPS Jitter Control Testbed and Bifocal Relay Mirror Testbed.
