Conventional integral imaging uses a fine fly‐eye lens whose elemental lens is perceived as one pixel. Coarse integral imaging uses a coarse fly‐eye lens so that multiple pixels are observed through each elemental lens, which generates a real image or a virtual image of the display panel. By using interleaved Fresnel lenses where the width of elemental prisms changes gradually, discontinuity of image due to the coarseness of lens array becomes indistinct. When multiple projection‐type display panels with high transmittance are layered, a layered real image or virtual image without moiré is formed, which enables integral imaging with volumetric features.
