Abstract

Segmented primary mirror has been widely used in high-resolution ground-based and space-based telescopes. In this paper, we mainly discuss the wavefront control issue for a segmented primary mirror with annular-sector subaperture. In order to balance the requirements of correction in amplitude and spatial frequency, we propose a multistage wavefront control strategy and allocate the wavefront errors in spatial frequency domain. The power spectral density (PSD) is calculated to obtain the spatial frequency information of wavefront aberrations. The feasibility of the control strategy is verified by numerical simulation.
