Integral imaging systems using interleaved Fresnel lenses and transmissive display panels

Abstract

Integral imaging reproduces the light-ray space of a scene to realize a 3D vision. In particular, a coarse integral imaging system, featuring elemental lenses large enough to cover more pixels than the number of views, holds promise in applications like interactive visualization systems and automobile head-up displays (HUDs) for 3D display. However, conventional coarse integral imaging and coarse integral volumetric imaging systems face challenges related to visible seams in the lens array and the emergence of moiré patterns caused by layered liquid crystal panels (LCDs), that significantly degrade image quality. This paper presents a solution to these problems by employing an integrated interleaved Fresnel lens sheet to achieve seamless 3D images with smooth motion parallax while using layered transmissive panels to generate volumetric images free from moiré.
