论文摘要
极化全息通常需要对极化敏感的全息图，以重建极化 - 培训全息图像或极化敏感的图像通道。迄今为止，极化全息图是琼斯基质方法的基础，该方法使用了包括超薄跨表面全息图在内的双向全息图，从而将极化控制限制为正交极化状态。在这里，我通过利用结构化矢量束的波前形状来介绍一个新颖的矢量波前全息概念。我将表明，相位全息图可用于定制动量空间中向量束的极化干扰，从而创建任意极化状态，包括但不限于线性，圆形，方位角和径向极化。这为全息图像中任意极化分布的多路复用产生打开了前所未有的机会。所展示的矢量波前全息图提供了柔性的极化控制，而无需使用双重光学材料，该材料可能会在极化成像，全息图，全息数据存储，多视图显示，多视图显示，全息图stokesmeter和极性计中找到应用。
Polarisation holography generally demands polarisation-sensitive holograms for reconstructing either polarisation-multiplexed holographic images or polarisation-sensitive image channels. To date, polarisation holography is underpinned by the Jones matrix method that uses birefringent holograms, including ultrathin metasurface holograms, limiting the polarisation control to orthogonal polarisation states. Here I introduce a novel concept of vectorial wavefront holography by exploiting the wavefront shaping of a structured vector beam. I will show that a phase hologram can be used to tailor the polarisation interference of a vector beam in momentum space, creating arbitrary polarisation states that include but not limited to the linear, circular, azimuthal, and radial polarisations. This opens an unprecedented opportunity for the multiplexing generation of arbitrary polarisation distributions in a holographic image. The demonstrated vectorial wavefront holography offers flexible polarisation control without using birefringent optical materials, which may find applications in polarisation imaging, holographic encryption, holographic data storage, multi-view displays, holographic Stokesmeter, and polarimetry.
