| 摘 要： | 研制了环形孔径锥镜剪切相机，并利用它进行激光散斑照相，测量物体的位移导数场。该相机一次实验即可在一张散斑图上同时记录物体所有各方向的位移导数场，且在全场滤波时连续再现各方向的位移导数场。

| Abstract: | In this paper, Annular aperture cone glass shearing laser speckle photography used for measuring the derivatives of displacements is proposed for the first time. The derivatives of displacements in all directions can be recorded simulataneously on one double exposed specklegram in one step , and the information of every direction can be obtained by whole-field filtering. |
