摘要
在衍射积分与波带法的基础上对无透镜夫琅和费衍射条件进行了分析比较,表明两种方法得出的夫琅和费衍射条件是一致的,且波带法有利于学生对夫琅和费衍射的理解.
Fraunhofer diffractive condition without a lens is compared based on diffractive integral and Fresnel＇s wave zone method, which proves that Fraunhofer diffractive condition obtained from the two methods is consistent. The method of Fresnel＇ s wave zone could help students to understand Fraunhofer diffraction better.
