摘要：
We study an adaptive dynamical feedback system for phasing of segmented mirrors. The system, which combines a Zernike wave front sensor with a feedback loop, is shown to be capable of separating (static) misalignment errors of segmented mirrors from (dynamical) atmospheric turbulence. Our numerical simulations establish that it can retrieve multi-wave segment misalignment error in the presence of large-amplitude atmospheric phase distortion.
