针对传统光学设计和校正手段无法有效消除空间光学成像系统在轨工作时受各种因素影响使像质变差的问题,提出把均匀设计的思想引入位相差异波前传感技术,对系统在轨工作时的波前畸变进行估计.从而实现了对系统波像差的全局优化估计,放宽了波像差的估计范围,易于实现并行化.通过仿真实验发现,该方法正确估计率高,抗噪声能力强,是进行空间光学成像系统波像差估计的有效方法.

Because traditional optical design and correction method are not able to eliminate the problem that the image quality is reduced by various factors. A basic principle of wave-front sensing using phase diversity is introduced. A new wave-front error sensing method is proposed which based on the combination of phase diversity with uniform design. It is a global optimization method which has the characters such as larger estimation range and good parallel efficiency. The simulation test results show that this method possesses high correct estimation rate and anti-noise performance. It is an effective method of wave-front error estimation for space optical imaging system.
