摘要
通过对自聚焦透镜衍射现象的分析和计算 ,阐述了引起此现象的原因是由于发散球面波出射端面的圆孔菲涅耳衍射 ,并提出一种作为检验自聚焦透镜质量的直观、简洁的方法 .
Through the analysis and calculation on the diffraction phenomenon of self-focus lens, it is explained that round-hole Fresnel diffraction of divergent spherical wave causes this phenomenon. And a concision method to measure the quality of self-focus lens is suggested based on such phenomenon.
