我们所提出的算法设计的三维（3D）结构可以同时表现出多个二维图案。3D结构通过分布伪影的效果来提供具有方向特性的多个图案。在本研究中，我们提出了一种迭代算法来提高所展示图案的图像质量，并使用数值模拟验证了所提出算法的有效性。此外，我们制作了不同的3D玻璃结构（一个八角棱镜，立方体和球体）使用所提出的算法。所有的3D结构都表现出四种图案，并且根据观察方向可以观察到不同的图案。(C)2016美国光学学会
A three-dimensional (3D) structure designed by our proposed algorithm can simultaneously exhibit multiple two-dimensional patterns. The 3D structure provides multiple patterns having directional characteristics by distributing the effects of the artefacts. In this study, we proposed an iterative algorithm to improve the image quality of the exhibited patterns and have verified the effectiveness of the proposed algorithm using numerical simulations. Moreover, we fabricated different 3D glass structures (an octagonal prism, a cube and a sphere) using the proposed algorithm. All 3D structures exhibit four patterns, and different patterns can be observed depending on the viewing direction. (C) 2016 Optical Society of America
