摘要
在讨论点源衍射的基础上,分析了衍射成像的基本原理,然后通过计算模拟探讨了影响衍射成像的因素,有利于改进光的衍射的教学以及培养学生理论分析和模拟计算的能力。
On the basis of the round hole diffraction irradiated by a point source, the basic principles of diffraction intaging are ana- lyzed. Then the influence factors of diffraction inutging are discussed through the sinulations. That is helpfid to improve light diffraction teachiog and to raise students＇ abilities of theoretical analysis and analog computation.
