title = "Wavefront sensing and control for a segmented primary mirror",
abstract = "Large-aperture segmented primary mirror has been widely used in high-resolution space telescopes. In this paper, we concentrate on the wavefront sensing and control (WFS&C) methods for a segmented primary mirror comprising a central octagon and eight surrounding petals. As the wavefront errors have a wide dynamic range in amplitude and spatial frequency, a multistage wavefront control algorithm is proposed. The control process is divided to five steps to reduce the wavefront errors gradually. A simulation toolbox integrating multi-disciplinary software has been developed to verify our WFS&C algorithms. Simulation results give a good demonstration of the feasibility of our algorithms.",
