Abstract：

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.　©　2025,　John　Wiley　and　Sons　Inc.　All　rights　reserved.
