Integral volumetric imaging with dual layer fly-eye lenses

This paper proposes an integral volumetric imaging system that uses a coarse fly-eye lens and a fine fly-eye lens to show smooth and deep 3D image. Conventional integral volumetric imaging displays using a coarse fly-eye lens have suffered from low image quality due to distinct seam of lenses and moiré pattern caused by layered panel structure. To solve these problems the proposed system uses a fine fly-eye lens whose elemental lens has a long focal distance. By placing a fine fly-eye lens near the layered real image, the seam and the moiré are removed while the degradation of the presented 3D image is kept small.
