In this paper , we analyzed the modulation of the interference intensity of each pixel on the time sequence speckle patterns in the time domain and proposed a new phase retrieve method , time sequence phase method ( tspm ) , in which the time sequence speckle interferograms are used to obtain the whole field deformation of the object
本论文通过对序列散斑图上各点在时间轴上散斑强度调制函数的变化进行分析，提出了一种基于时间序列的散斑干涉场的相位解调方法，进而获得物体全场变形信息。
