| 摘 要： | 光学超分辨、焦深扩展及焦移3种效应一直受到研究人员的关注,且在光学显微成像、光学校准、光学相干层析成像及光存储中有着重要的应用.提出一种可调谐光瞳滤波器来实现光学系统的轴向焦移及扩展焦深.该光瞳滤波器由两个完全相同且相互平行的λ/4波片和置于其间的λ/2波片组成,其中λ/2波片分为两个可作相对旋转的区域,并且通过推导得...

| Abstract: | Optical superresolution,focal shift and high focal depth in optical imaging system have been the goal of many researchers and have widely application in the optical microscopy,optical alignment and optical coherent tomography systems.A tunable pupil filter for modulation of axial focal shift and extended focal depth is proposed.It consists of one half-wave plate located between two identical and parallel quarter wave-plates,the half-wave plate is made up of two zones that can rotate with respect to each oth... |
