Hologram Interlacing with Diagonal Offset

原文（中文）

A holographic projection system arranged to display a target picture and a method of holographic projection is disclosed. A hologram comprises a first sub-hologram corresponding to a first picture area of a picture and a second sub-hologram corresponding to the second picture area of the picture. The first and second picture areas are spatially displaced in at least one of first and second orthogonal dimensions. A portion of a holographic wavefront corresponding to the first-sub-hologram is steered in a first diagonal direction with respect to a propagation axis. A portion of a holographic wavefront corresponding to the first-sub-hologram is steered in a second diagonal direction with respect to a propagation axis. The second diagonal direction is different from the first diagonal direction in at least one of the first and second dimensions.
