摘要
以激光散射、干涉及衍射理论为依据,研究动态散斑及多普勒效应形成原因,论述两种物理效应的理论基础及相互关系,用实验方法说明物体表面散射元数目及弱散射体对散射场强度起伏的影响,得出动态散斑与多普勒效应的实验方法相同,应用互补性强,仅在两种物理效应的理论解释方面有差异的结论。
Based on the theory of laser scattering, interference and diffraction, we investigated the cause of dynamic Speckles and Doppler effect, probed intothe basement of these two effects and their relationship, and elucidated the influence of scatterer number on object surface on in- tensity fluctuation of scatter field with tests as well. We elicited that the tests method of dy- namic Speckles and Doppler effect are common with high application compensation, and there merely existed some differences in the theory explain of these two physical effect.
