本文首次提出利用菲涅耳透镜组成的大口径阴影光学系统.实验表明,该系统能满足一般阴影摄影要求.这种尝试既扩大了菲涅耳透镜的应用范围,也为阴影光学系统向大孔径发展开辟了新途径.
This paper presents for the first time a large-aperture shadow optical system using Fresnel lens.The experiment shows that the system can meet the general shadow photography requirements.This attempt not only expand the scope of application of Fresnel lens, but also for the shadow optical system to the large aperture Development opened up new ways.
