通过纳米级3D打印实现高分辨率光场打印
High-resolution light field prints by nanoscale 3D printing
摘要：
光场打印（LFP）在环境白光照明下向裸眼观察者显示三维（3D）信息。观察者从不同的角度看到3D图像的变化视角。然而，由于有限的分辨率和透镜与彩色像素之间的未对准，LFP出现像素化。创建高分辨率LFP的一个有前途的解决方案是通过使用先进的纳米纤维技术。在这里，我们使用双光子聚合光刻作为一步纳米级3D打印机，直接从透明树脂中制造LFP。这种方法同时产生高空间分辨率（29 - 45 μm）和高角分辨率（~ 1.6 °）图像，在15个{ \times } 15视图上具有平滑的运动视差。值得注意的是，最小的彩色像素仅由单个纳米柱（直径约300 nm）组成。我们的LFP标志着向超现实3D图像迈出了一步，可应用于印刷媒体和高价值商品的安全标签。
英文摘要：
A light field print (LFP) displays three-dimensional (3D) information to the naked-eye observer under ambient white light illumination. Changing perspectives of a 3D image are seen by the observer from varying angles. However, LFPs appear pixelated due to limited resolution and misalignment between their lenses and colour pixels. A promising solution to create high-resolution LFPs is through the use of advanced nanofabrication techniques. Here, we use two-photon polymerization lithography as a one-step nanoscale 3D printer to directly fabricate LFPs out of transparent resin. This approach produces simultaneously high spatial resolution (29 - 45 μm) and high angular resolution (~ 1.6 °) images with smooth motion parallax across 15 {\times} 15 views. Notably, the smallest colour pixel consists of only a single nanopillar (~ 300 nm diameter). Our LFP signifies a step towards hyper-realistic 3D images that can be applied in print media and security tags for high-value goods.
