Paper Abstract

We investigate the feasibility of using an adaptive mirror for in-orbit aberration corrections. The advantage of an in-situ aberration correction of optical components in the space environment is that the mirror shape can be adjusted in an iterative fashion until the best image is obtained. Using the actuator spacing, corresponding to one-half the Nyquist frequency, the Strehl ratio of the corrected wavefront improves to 0.95 when the mirror is fabricated with 6.5 waves of spherical aberration. The Strehl ratio is decreased to 0.86 when the number of actuators is reduced by a factor of 4, in a 2D adaptive optics model.
