This project will carry out experiments to study the performance of advanced strategies for adaptive optics, a cutting-edge modern technology that uses fast-moving deformable mirrors to rapidly compensate for the fluctuations in image quality produced by the shimmering atmosphere. Adaptive optics has flourished in recent years, delivering dramatically sharper images but usually only over a rather limited portion of the sky. The technical innovations to be investigated under this program will utilize multiple deformable mirrors optically matched to different layers of the turbulent atmosphere, and this "multi-conjugate" approach will result in high-quality corrected images over a substantially larger region of the sky.The adaptive optics system at the 1.6 meter solar telescope at Big Bear, CA, has delivered high-quality solar images in a single-deformable-mirror mode, providing detailed information about complex spatial structures on the surface of the sun at unprecedented spatial scales. The system features three deformable mirrors, each having 357 actuators, and multiple pupil positions in which the deformable mirrors may be placed. When considering the more complex architecture of an adaptive optics system capable of a multi-conjugate observing mode, a number of technical issues have yet to be addressed. These issues include such fundamental questions as the optimum placement in the beam train of deformable mirrors and wavefront sensors. The current project will address these issues directly, experimentally. A number of science goals, including the onset and evolution of solar flares, flare triggering mechanisms, and magnetic reconnection events, require diffraction-limited observations over the large field of view promised by the multi-conjugate observing mode.In addition to providing training for the next generation of instrumentation scientists, these investigations by their potentially path-finding nature will provide a vital form of broader impacts in advancing the art of adaptive optics at many observatories, for both solar and night-time observations.Funding for this project is being provided by NSF's Division of Astronomical Sciences through its Advanced Technologies and Instrumentation program.

该项目将进行实验，以研究自适应光学策略的性能，这是一种尖端的现代技术，它使用快速移动的可变形镜子来迅速弥补闪闪发光气氛产生的图像质量波动。 近年来，自适应光学元件蓬勃发展，产生了巨大的图像，但通常仅在有限的天空中。 The technical innovations to be investigated under this program will utilize multiple deformable mirrors optically matched to different layers of the turbulent atmosphere, and this "multi-conjugate" approach will result in high-quality corrected images over a substantially larger region of the sky.The adaptive optics system at the 1.6 meter solar telescope at Big Bear, CA, has delivered high-quality solar images in a single-deformable-mirror mode, providing关于前所未有的空间尺度，有关太阳表面上复杂的空间结构的详细信息。 该系统具有三个可变形的镜子，每个镜子都有357个执行器，并且可以放置可变形镜的多个瞳孔位置。 在考虑能够进行多种轭观测模式的自适应光学系统的更复杂的体系结构时，尚未解决许多技术问题。 这些问题包括在可变形镜和波前传感器的梁列中最佳放置等基本问题。 当前的项目将直接，实验地直接解决这些问题。许多科学目标，包括太阳耀斑的发作和演变，耀斑触发机制和磁重新连接事件，都需要在多个偶联观察模式所承诺的较大视野上进行衍射限制的观察，此外，除了为下一代仪器科学的范围提供培训，还可以为范围提供培训，从而为这些仪器提供范围，这些仪器的范围将构成范围的范围。在许多观察者中，对于太阳能和夜间观察。
