We propose a dual-side see-through integral imaging 3D display based on a lens array holographic optical element (LAHOE). The display system consists of two projectors and a LAHOE. The LAHOE is fabricated according to the theory of reflective volume holograms. An interference pattern is formed by a plane-wave beam and a spherical-wave array beam, and the interference pattern is recorded into a photopolymer material. Thus, the LAHOE is formed. When a reference beam is projected into the LAHOE, the wavefront of a convex micro-lens array is reconstructed. When a phase conjugation reference beam is projected into the LAHOE, the wavefront of a concave micro-lens array is reconstructed. So, the LAHOE possesses the optical properties of a convex micro-lens array and a concave micro-lens array. The proposed display is developed using integral imaging principle and it realizes dual-side see-through integral imaging 3D display.

我们提出了一种基于透镜阵列全息光学元件 (LAHOE) 的双面透视整体成像 3D 显示器。显示系统由两台投影仪和一台LAHOE组成。LAHOE 是根据反射体全息图的理论制造的。由平面波光束和球面波阵列光束形成干涉图案，并将干涉图案记录到光敏聚合物材料中。因此，形成了LAHOE。当参考光束投射到 LAHOE 中时，凸微透镜阵列的波前被重建。当相位共轭参考光束投射到 LAHOE 中时，凹面微透镜阵列的波前被重建。因此，LAHOE 具有凸微透镜阵列和凹微透镜阵列的光学特性。
