| 摘 要： | 菲涅耳波带片可使入射光会聚起来，产生极大的光强，使点光源形成一系列的实像点和虚像点，其作用如同透镜成像。利用半波带分析法可分析菲涅耳波带片对称轴上的点光源通过菲涅耳波带片成像时像点在对称轴上的分布及 焦距的变化情况。

| 关 键 词： | 菲涅耳波带片 成像 像点 焦距 |

| Abstract: | Fresnel's plate can focus incident rays, producing very strong brightness, the function of which resembles lens forming images. The analytical method of the half-wave plate can be used to analyze the changes in the distribution and focal distance on the symmetrical axis of the images when the image of the spot ray resource of Fresnel's plate on the symmetrical axis goes through Fresnel's plate. |

| Keywords: | Fresnel's plate formation of images image forcal distance |
