Advanced Phase Diversity Techniques for Fire-Resolution Solar Astronomy

AST-9731167摘要资金将用于开发相位多样化散斑技术，用于大气波动引起的太阳图像像差的探测后校正。这项工作将把PDS技术的用途扩展到窄带、偏振和光谱数据集。采用最优和统一估计器的新的重建算法将通过类似于当前的PDS算法来开发。此外，还将在正则化(抑制噪声放大)、空间可变模糊和时间序列处理方面对当前算法进行改进。

AST-9731167 ABSTRACT Funds will be used for development of the Phase Diverse Speckle (PDS) technique for the post-detection correction of aberration of solar images due to atmospheric fluctuations. The effort will extend the utility of the PDS technique to narrow-band, polarimetric, and spectroscopic data sets. Novel reconstruction algorithms that employ optimal and unified estimators will be developed by analogy to current PDS algorithms. In addition, refinements to current algorithms with regard to regularization (suppression of noise amplification), space-variant blur, and time-series processing will be made.
