摘 要: Toraldo光瞳是超分辨中研究最多的光瞳之一 .不过 ,由于实际中在制作精确度以及制造效率上的限制 ,它的应用受到了很大程度的制约 .提出了双Toraldo光瞳的共焦系统 。 Toraldo pupil filter has been one of the most popular pupil filters. But its use is restricted because of the fabrication. In this article, we propose a confocal system with two Toraldo pupil filters. The function of a multi-zone Toraldo pupil filter, which is difficult to fabricate can be substituted by two relatively simple Toraldo pupil filters.
