Tiled arrays use modulo-2π phase compensation and coherent beam combination to correct for the effects of deep turbulence. As such, this paper uses wave-optics simulations to compare the closed-loop performance of tiled arrays to a branch-point-tolerant phase reconstructor known as LSPV+7 [Appl. Opt.53, 3821 (2014)10.1364/AO.53.003821]. The wave-optics simulations make use of a point-source beacon and are setup with weak-to-strong scintillation conditions. This setup enables a trade-space exploration in support of a power-in-the-bucket comparison with LSPV+7. In turn, the results show that tiled arrays outperform LSPV+7 when transitioning from weak-to-strong scintillation conditions. These results are both encouraging and informative for those looking to tackle the branch-point problem in adaptive optics.
拼接阵列使用模2π相位补偿和相干光束合成来校正深度湍流的影响。因此，本文使用波动光学模拟来比较拼接阵列与一种名为LSPV+7的耐分支点相位重建器的闭环性能[《应用光学》53, 3821 (2014)10.1364/AO.53.003821]。波动光学模拟使用点源信标，并设置了从弱到强的闪烁条件。这种设置能够进行权衡空间探索，以支持与LSPV+7进行桶中功率比较。相应地，结果表明，在从弱闪烁条件过渡到强闪烁条件时，拼接阵列的性能优于LSPV+7。这些结果对于那些希望解决自适应光学中的分支点问题的人来说既令人鼓舞又具有参考价值。
