Hologram Interlacing with Diagonal Offset

A method for holographic projection of a picture comprising first and second picture areas arranged side-by-side in a first dimension, wherein the method comprises:

• displaying a hologram of the picture, the hologram comprising a first sub-hologram corresponding to the first picture area and a second sub-hologram corresponding to a second picture area;
• illuminating the hologram with light to form a holographic wavefront, wherein the holographic wavefront extends in the first dimension and a second dimension perpendicular to the first dimension and propagates in a third dimension perpendicular to the first and second dimensions;
• turning light of a first portion of the holographic wavefront by a first diagonal turn with respect to a propagation axis, wherein the first portion of the holographic wavefront is formed by the first sub-hologram, and
• turning light of a second portion of the holographic wavefront by a second diagonal turn with respect to the propagation axis, wherein the second portion of the holographic wavefront is formed by the second sub-hologram and wherein the second diagonal turn is different to the first diagonal turn.
