| 摘 要： | 本文提出了旋转孔径散斑照相的逐点分析法,其杨氏花纹一般来说不是等距离的直条纹,而是与位移的动态过程相联系的曲线条纹.本文解释了这种条纹的意义,给出了理论分析和实验证明.

| Abstract: | In this paper, we make a point-wise analysis of a specklegram made by rotating aperture method for speckle photography. The Young's pattern is generally not equal spaced straight fringes, but curved fringes according to the dynamic process of displacements. In this paper, the meaning of the pattern is explained, theoretical analysis and experimental demonstration are presented. |
