Abstract

Light field prints (LFPs) display three-dimensional (3D) information to the naked eye under ambient white light illumination. However, current LFPs suffer from pixelation due to limited resolution and misalignment. This paper uses two-photon polymerization lithography to directly fabricate high-resolution LFPs from transparent resin, achieving high spatial (29–45 µm) and angular (~1.6°) resolution images with smooth motion parallax. The smallest color pixel uses a single nanopillar (~300 nm diameter). This method offers a step towards hyper-realistic 3D images applicable to print media and security tags.
