| 摘 要： | 本文首次提出一种散斑剪切相机。该相机能把曲率、扭率和斜率的二维信息同时记录在一张双曝光散斑图上。对散斑图进行滤波分析时在频谱面上出现十三块互不重叠的衍射晕。在适当的衍射晕上滤波即可获得二维曲率、扭率和斜率的等值全场条纹。

| Abstract: | n this paper, a new speckle shearing camera is designed for simultaneous recording 2-D curvature, twist and slope on a double exposed specklegram. The specklegram yieldsthirteen distinct diffraction halos when subjected to filtering. The curvature, twist and slope fringes can be obtained by filtering via the appropriate halos. |

| Keywords: | five-shearing camera curvature twist slope central difference |
