Advanced Phase Diversity Techniques for Fine-Resolution Solar Astronomy

资金将用于发展相位变化散斑（PDS）技术，用于探测后校正由于大气波动引起的太阳图像像差。这项工作将把PDS技术的应用扩展到窄带、偏振和光谱数据集。采用最优和统一估计量的新型重建算法将通过类比现有的PDS算法来开发。此外，对当前算法的正则化（抑制噪声放大）进行了改进

AST-9817796PAXMANABSTRACTFunds 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
