关键词： 全息；两重体全息光栅波导；二维扩瞳；视场扩展

摘要： 为扩大体全息光栅波导的出瞳直径和视场，提出了二维扩瞳和视场扩展的两重体全息光栅波导设计方法。该波导结构的出耦合光栅由两个两重体全息光栅构成，用于实现二维扩瞳。将入射视场分为两条路径传播，每条路径负责一半的视场，最后将两部分视场拼接形成完整视场。该方法不仅扩大了出瞳直径，还有利于增大全息波导系统的视场 ...

关键词： 相位成像；超表面；剪切干涉；涡旋相衬

摘要： 相位是光场信息的重要组成部分。在光学显微成像领域，大部分生物细胞对光的吸收较弱，传统的亮场显微无法准确地表征细胞的结构特征，因此相位成像成为非标记细胞观测的重要方法。经典的相衬显微镜基于干涉成像原理，通常需要大块的折射棱镜或者复杂的成像系统，因而系统臃肿，易受环境扰动。超表面是一种特征尺寸在纳米或微 ...
