Speckled Speckle中的奇点:统计

Singularities in Speckled Speckle: Statistics

Isaac Freund, David A. Kessler

摘要:

具有两个非常不同的相关长度的随机光场产生远场散斑,其本身是高度散斑的。我们称这种图案为斑点斑点,并使用分析理论和计算机模拟来研究它们的临界点(奇点和稳定点)。我们发现异常的临界点和数量级异常的相对数密度的空间排列,并在相关的零交叉的密度。

英文摘要:

Random optical fields with two widely different correlation lengths generate far field speckle spots that are themselves highly speckled. We call such patterns speckled speckle, and study their critical points (singularities and stationary points) using analytical theory and computer simulations. We find anomalous spatial arrangements of the critical points and orders of magnitude anomalies in their relative number densities, and in the densities of the associated zero crossings.
