Tomographic wavefront sensing for adaptive optics

ABSTRACTDekany, R。利用一种新的多通道波前传感器与现有的帕洛玛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，以重建帕洛玛山5m望远镜折射率波动的三维分布。这些信息将用于回答有关这些指数波动的时间演变的基本问题，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镜子来均匀地校正宽视场，扩展自适应光学的可用科学领域，并实现新的科学计划

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.***
