Session 60 - Next Generation Space Telescope.
Oral session, Tuesday, January 14
Piers 4/5,
The imaging performance of a NGST is degraded by thermal deformation, vibration, attitude control noise, imperfect optics and other effects. Performance is restored through active and adaptive optical control, coupled with a system design process that crosscuts the structural, thermal, optical and control subsystems. Integrated computer modeling tools enable accurate prediction of NGST performance as a function of design parameters from these subsystems. Detailed closed-loop imaging performance results are presented to illustrate specific system architecture issues.
