19 May 2005 Large dynamic range wavefront control of micromachined deformable membrane mirrors
Author Affiliations +
Micromachined deformable membrane mirrors (MDMMs) are currently being integrated into or proposed for numerous space-based imaging applications, including systems that utilize phase diversity, foveated imaging, and active or adaptive optical zoom. In stark contrast to applications that require only a few waves of optical stroke, such as atmospheric turbulence correction, these applications often require that the mirrors operate over much larger dynamic ranges. In order to obtain near diffraction-limited performance, these mirrors must be capable of producing wavefronts with accurate figures to within a quarter-wave (P-V). Recent experimental results will be discussed, in which MDMMs produced focal lengths as low as 2.5m with near diffraction-limited performance.
