摘要:

A three‐step method is described for obtaining holograms of 3D objects illuminated in white light. A horizontal linear array ofnlenslets is used to simultaneously photograph a 3D scene. The resulting array ofn2D images is transformed into a thin horizontal strip hologram, using coherent light. Multiple (n) identical copies of this strip hologram are contiguously arranged in a vertical column, resulting in ann×narray of elemental holograms for viewing of the virtual image of the 3D scene. Horizontal parallax is preserved; vertical parallax is sacrificed to reduce the bandwidth required for transmission by a factorn.
