散斑中的奇点:屏蔽
Singularities in Speckled Speckle: Screening
摘要:
研究了两种不同长度尺度的随机光场中光学奇点的屏蔽问题。我们称这种场产生的散斑图案为斑点状散斑,因为图案中的主要散斑斑点本身是高度斑点状的。我们研究组合的领域,其组件表现出短期和长期的相关性,并找到不寻常的形式的筛选。
英文摘要:
We study screening of optical singularities in random optical fields with two widely different length scales. We call the speckle patterns generated by such fields speckled speckle, because the major speckle spots in the pattern are themselves highly speckled. We study combinations of fields whose components exhibit short- and long-range correlations, and find unusual forms of screening.
