摘　　要：采用两套旋转孔径散斑照相系统对动态三维位移场进行了研测。一次实验可把缓慢连续变形体的动态三维位移场的整个变化过程记录于两张散斑图上．对散斑图进行全场滤波可摄取所有各时刻的三个位移分量的信息。A 3-D dynamic displacement field is studied and tested by use of two sets of rotation aperture spackle photographic system.In one experiment,the whole changing procedure of the dynamic 3-D displacement fied of a slowing continuously deforming body can be recorded on two speckle patterns.Through the all-field fliting of speckle pattern,all informations of the three displacement components at any time can be extracted.
