| 中文摘要: |
| 研究柱面波照明的周期性物体的自成象现象,推出了光场分布的表达式。由于物体的自成象不仅周期有变化,而且方向也改变,故分析了其自成象和另一块光栅形成的莫尔条纹的特点。 |
| 英文摘要: |
| The self-image phenomenon of a periodic object illuminated by calindrical wave is described. The expressions of propagating field are derived. it shows that not only the period of self-image is changed, but also the direction of the self-image is changed too. And the feature of Moire fringes formed by the image and another grating is analysed. |
