    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.
