We propose a photon-sieve hologram (PSH), a novel computer-generated hologram for generating an image with a resolution of the order of the wavelength. The PSH is designed by synthesising many photon sieves. The PSH has a simple structure that consists of pinholes with the same sizes and depths, and it directly generates images without other optical elements such as masks and imaging optical system. It is advantageous for image generation in ultraviolet and x-ray bands, where high-transmittance and high-numerical-aperture optical systems are difficult to build. In this study, we introduce a sparse photon sieve to configure the PSH and describe the principle of image generation and design procedure. We also fabricate PSHs that generate a line image and a broken-line image to demonstrate phase controllability, and skew images for three-dimensional image generation.

由光子筛组成的具有波长顺序分辨率的无透镜计算机生成的全息图

我们提出了一种光子筛全息图（PSH），这是一种新颖的计算机生成的全息图，用于生成分辨率为波长量级的图像。PSH是通过合成许多光子筛而设计的。PSH具有简单的结构，该结构由具有相同大小和深度的针孔组成，并且无需其他光学元件（如掩模和成像光学系统）即可直接生成图像。对于在难以建立高透射率和高数值孔径光学系统的紫外线和X射线带中生成图像而言，这是有利的。在这项研究中，我们介绍了一种稀疏光子筛来配置PSH，并描述了图像生成和设计程序的原理。我们还制作了可生成线图像和虚线图像的PSH，以证明相位可控性，
