- P‐9.13: Design and Optimization of Triple‐focal Microlens Array for Integral Imaging 3D Display Yuyan Peng Wenwen Wang Xiongtu Zhou Tailiang Guo Qun Yan Chaoxing Wu Yongai Zhang SID Symposium Digest of Technical Papers The near‐eye display device, based on naked eye 3D display technology, holds significant potential as a next‐generation display for the metauniverse, offering a new way to interact with digital content. Integral imaging (II) naked eye 3D display, with its advantages, such as full parallax, full color, and good compatibility, shows great commercial promise. Depth of field (DoF) is a critical factor for creating immersive 3D experiences, allowing viewers to engage deeply with the content. This paper proposes a triple‐focal microlens array (TF‐MLA) with a honeycomb arrangement to simultaneously improve DoF and resolution for II 3D display. Firstly, the imaging principles of II 3D display based on the TF‐MLA was analyze and the DoF formula was derived. Then the TracePro optical simulation software was applied to simulate the light field reconstruction process of the TF‐MLA II system to investigate the effects of object distance and image distance on display performance. Results show that traditional II system has only one central depth plane, while the TF‐MLA create three distinct central depth planes, enabling the reconstruction of 3D objects at three different depths simultaneously. The DoF of the TF‐MLA II system is 3.5 times that of the traditional II system. 10.1002/sdtp.19085 http://onlinelibrary.wiley.com/termsAndConditions#vor
