Abstract

This invention relates to methods, apparatus, and computer program code for the holographic display of images. We describe a method of displaying an image holographically, the method comprising displaying a hologram on pixels of a spatial light modulator (SLM) and illuminating said SLM such that said image is displayed in pixels of a replay field (RPF) of said hologram, and wherein the method further comprises subdividing said replay field into a plurality of spatially interlaced regions, and displaying holograms for each of said interlaced regions of said replay field sequentially at different times such that in an observer's eye said interlaced regions integrate to give the impression of said image and such that interference between adjacent pixels of said replay field is reduced.
