模式耦合对倾斜校正自适应光学系统的非等晕限制
-
摘要: 分析了当入射信标波前与观测目标不在同一方向且考虑模式之间的耦合时，倾斜校正自适应光学系统的波前残余误差。并引入模式耦合因子变量，分析了模式耦合对倾斜校正自适应光学系统波前校正残余误差的影响。此外还给出了光波水平大气传输时的数值计算结果。Abstract: The residual phase variance for tip-tilt correction adaptive optical system is analyzed by considering the modal coupling. The modal coupling coefficient, is introduced to analyze the effect of the modal coupling on the anisoplanatism limitation of the tip-tilt correction adaptive optical system. Furthermore, the numerical results for the light beam horizontal atmospheric propagation are presented.
