Holographic display apparatus |
摘要 |
A holographic display apparatus reconstructs an image by projecting a beam of a luminous source to a holographic sheet including a plurality of holograms. The holograms are arranged so that the central axes of images recorded in the holographic sheet are directed in a same direction, in the diverging direction, or in a converging direction. Additionally, each hologram has a first focal distance f1 (mm) and a second focal distance f2 (mm) which are in a relationship such that f1</=f2/28+50 and f1<f2.
