Correcting Surface Figure Error in Imaging Satellites Using a Deformable Mirror

reportActive / Technical Report | Accession Number: ADA620500 | Open PDF

Abstract:

A deformable mirror is proposed as a solution to correct aberrations on a satellite primary mirror surface. The deformable mirror is used in a double-pass configuration with an interferometer and a mirror segment on the Naval Postgraduate School Segmented Mirror Telescope to test the ability of a deformable mirror to correct inherent surface figure aberrations of an imaging satellite mirror surface. Manual, iterative feedback, and constrained optimization control methods are used to control the deformable mirror to correct surface figure error on the Segmented Mirror Telescope mirror segments to achieve 55 root mean square improvement for the primary mirror segment surface.
