Rotating aperture speckle photography for measuring dynamic out-of-displacements
-
摘要: 本文提出利用旋转孔径进行散斑照相,研测动态离面位移场.该法能在一张散斑图上同时记录物体动态离面位移的全部过程,全场滤波可得任意时刻的瞬态离面位移场.Abstract: In this paper, the rotating aperture speckle photography used for measuring the dynamic out-of-displacements is proposed. The whole process of the dynamic out-of-displacements of an object can be recorded on a single speckle pattern. And by means of the whole field filtering,the out-of-displacements of every moment can be obtained.
