摘要: 激光导星可以部分解决自适应光学系统信标难题。给出典型激光导星自适应光学系统主要误差空间功率谱的简化计算模型。与常用的Monte-Carlo类型的模拟相比，该模型提供了激光导星自适应光学系统性能随主要控制参数变化的一种快速有效的评估手段。Abstract: The so-called beacon difficulty in adaptive optics can be partly overcome by applying laser guide star subsystem. The simplified calculation model for spatial power spectra of main error in a laser guide star adaptive optics system is presented. Compared with the commonly used Monte-Carlo method, this method is more efficient and faster to evaluate the performance of such laser guide star adaptive optics system.
