ABSTRACTDekany, R."Tomographic Wavefront Sensing for Adaptive Optics"AST-0096928Using a new, multiple channel wavefront sensor in conjunction with theexisting Palomar Adaptive Optics System, the researchers will conduct experiments in atmospheric tomography to reconstruct the three-dimensional distribution ofrefractive index fluctuations about the 5m telescope at Palomar Mountain.This information will be used to answer fundamental questions on the timeevolution of these index fluctuations, including the stability of discreetturbulence layers in the atmosphere. This information will guide thedevelopment of future advanced adaptive optics systems that use multipledeformable mirrors to uniformly correct wide fields of view, extending theusable scientific field for adaptive optics and enabling new scientificprograms.***

德卡尼河“用于自适应光学的层析成像波前传感“AST-0096928使用一种新的多通道波前传感器与现有的Palomar自适应光学系统相结合，研究人员将进行大气层析成像实验，以重建三个-在Palomar山的5米望远镜的折射率起伏的空间分布。这些信息将被用来回答这些指数的时间演化的基本问题波动，包括大气中离散湍流层的稳定性。 这些信息将指导未来先进自适应光学系统的发展，该系统使用多个可变形反射镜来均匀校正宽视场，扩展自适应光学的可用科学领域并实现新的科学计划。
