中文摘要：以散射、干涉及衍射为依据,对动态散斑及多普勒效应成因进行了分析,研究两种物理效应的理论基础及相互关系,用实验方法说明散射及动态散斑间的内在联系,进一步通过分析物体表面散射元数目对两种物理效应的约束能力来佐证两种物理效应的关联性。通过分析得出,在激光多普勒条件下,两种物理效应在本质上具有一致性,多谱勒效应能造成散射光强度振荡,这种强度振荡与动态散斑场的强度起伏密切相关。

外文摘要：Based on the theory of laser scattering, interference and diffraction, the cause of dynamic speckles and Doppler effect is investigated in order to probe into the basement of these two effects and their relationship, to elucidate the influence of scatterer number on object surface, and to evident on connection of two physieo-effects. Through ~omparing and analyzing, it is concluded that is essential to the characteristic of two physieo-effects under laser Doppler.
