| 摘 要： | 本文中导出了单色准直光倾斜入射时塔宝距离(Talbot Distance)的新公式,并给出了实验验证。塔宝效应还被成功地用于改进面内及影栅云纹方法,显著提高了这两种方法的灵敏度,并加大了参考栅与试件间的允许距离。

| Abstract: | Talbot effect is used to improve in-plane and shadow moire methods. For this purpose, a new formula for Talbot distances under inclined incidence is derived. As a result, the sensitivity of measurement is improved and the possible distance between referense grating and specimen is extended. |

| Keywords: | Talbot effect in-Plane moire shadow moire |
