摘要：

研究了大气热晕效应自适应光学(adaptive-optics, AO)位相补偿数值模拟方法。利用自主开发的高能激光大气传输四维数值模拟程序对准直光束瞬态热晕位相补偿进行了模拟，定量分析了不同的热晕强度下，AO系统空间带宽对位相补偿效果的影响。数值模拟结果表明，当热晕比较弱时，空间带宽对位相补偿效果的影响不大；当热晕比较强时，空间带宽越大，位相补偿效果越差。当热晕强度大于某一阈值时，在一个风渡越时间内，产生了位相补偿不稳定性(phase compensation instability, PCI)，空间带宽越大，发生PCI的阈值越小。

Abstract:

The numerical simulation method of thermal blooming adaptive optics (AO) phase compensation is studied. Collimated beam instantaneous thermal blooming phase compensation is simulated by using the laser atmospheric propagation four-dimension (4-D) code which is independently developed. The effect of deformable mirror (DM) actuators layout on the phase compensation efficiency under different thermal blooming strengh is numerically analyzed. The result shows that the layout of DM actuators has great effect on the AO system close-loop control stability. When the layout of DM actuators is different, the variance of DM actuators commands is also different. The proper layout of DM actuator can improve the AO system close-loop control stability, increase the threshold value of phase compensation instability (PCI).

Key words: adaptive optics, thermal blooming, deformable mirror actuators layout, phase compensation instability, numerical simulation
