Optimization Design of Wavefront Control Dimension for Adaptive Optics System of Space Camera

Wavefront control system is used to realize real-time correction of wavefront distortion in the adaptive optics system. Relevant parameters of the wavefront control system suitable for the background of space application are proposed to achieve the best performance of the adaptive optics system. In view of the working background of space camera, the main source of aberration is the primary aberration in low-order Zernike mode. At present, the core component of the wavefront control part of the adaptive optics system is the continuous planar piezoelectric deformable mirror, and the analysis method of the control voltage is usually the planar fitting principle. Based on the least square solution method of the wavefront fitting matrix, the optimal design method of the control voltage dimension is proposed in this paper.
