| Abstract: | In this paper, rotating aperture cone glass shearing speckle photography used for dynamic problems is proposed. The whole dynamic process can be recorded on a single specklegram, and the derivatives of displacements of every moment can be obtained by whole-field filtering. |

| Keywords: | rotating aperture cone glass derivatives of displacements shearing speckle photography |
