基于激光钠导星的星载自适应光学系统

用于对地观测的星载光学系统受空间环境及相机内环境的影响而存在波前畸变问题，从而导致成像质量变差。为获得分辨率达到近衍射极限水平的图像，需要利用自适应光学技术对波前畸变进行自适应光学校正。提出了一种基于星外信标的自适应光学系统实现畸变波前校正的方案，并给出仿真实验，从而为星载自适应光学的进一步研究提供了依据。

The Space-borne Adaptive Optical System Based on Laser Guide Star

The wavefront distortion often appears in the to-ground space-borne optical system that is subject to spatial circumstance and internal environment inside the camera, which result in poor image quality. To obtain fine image whose resolution could reach the limitation of near-diffraction, adaptive optical system is chosen to correct the wavefront distortion. In this paper, an adaptive optics scheme to compensate the wavefront is discussed. A numerical model is presented, and the corresponding simulation result is given. It is found that the adaptive optics based on the laser guide star are feasible for the wavefront correction of air-borne optics.
