散斑空间尺度及动态散斑分析

Formation and Structural Analysis of Speckles

以干涉、衍射及散射理论为基础介绍了散斑的形成、分类,并根据杨氏干涉及菲涅尔衍射理论.推导出静态散斑横向尺度及纵向尺度,给出了散斑的空间形状并对静态散班和动态散斑作了分析,总结出动态散斑三个衍射带的基本特点。

Mased on the interference, diffraction and scatter theory, we study formation, type and scale size of speckle, deduce transveral and vertical speckle measure on the basis of Young＇ s interference and diffraction theor in order to provide the speckle space pattern. We have detalied introduction and theoretical analysis between static and dynamic speckles and draw a result that in three diffractional lines on dynamic speckles posses self characteristic.
