| 摘 要： | 本文从菲涅尔——基尔霍夫积分出发,在菲涅尔近似条件下,讨论了无准直透镜时扩展光源照明任意平面周期衍射物的 Talbot 效应。结论表明,在这种情况下无法直接观察到 Talbot 像。这一结论和实验结果吻合。并指出要获得 Talbot 像,必须经过滤波处理。

| Abstract: | In this paper,the Talbot effect in illumination of any type of periodic plane object by extended light source is studied with the aid of Fresnel-Kirchhoff integral in Fresnel approximation.The conclu- sion shows that Talbot images do not exist under such conditions, which coincides with the results of the experiment made by the author. It is also pointed out that filtration is needed if Talbot images are to be obtained. |
