AST-0123466Roggemann, Michael C.This work will develop and validate a technique to derive long exposure Point Spread Functions as a function of Field of View using on-axis wavefront statistics measured at the Advanced Electro-Optical System adaptive optics wavefront sensor. The technique will use existing models of the well-characterized turbulence profiles at the Maui site on Haleakela. This approach, if demonstrated successfully, may lead to a new technique that will be an alternative to the more expensive and complex Multiple Conjugate Adaptive Optics systems planned for the future. It promises to be a useful tool for the entire astronomy community studying extended objects.***

AST-0123466 Roggemann，Michael C.这项工作将开发和验证一种技术，使用在高级光电系统自适应光学波前传感器上测量的轴上波前统计数据，推导出作为视场函数的长曝光点扩散函数。这项技术将使用Haleakela上毛伊岛站点现有的具有良好特征的湍流剖面模型。这种方法如果成功演示，可能会导致一种新的技术，这将是未来计划中的更昂贵和更复杂的多共轭自适应光学系统的替代方案。它有望成为整个天文学团体研究扩展天体的有用工具。*
