1. A computer-readable medium having instructions stored thereon that, in response to execution by at least one device, cause the at least one device to perform operations comprising: illuminating an electrically addressed spatial light modulator (EASLM) with coherent light; displaying a computer generated hologram (CGH) image on the EASLM so as to diffract light therefrom to produce a two dimensional image at a display surface; sub-dividing the two dimensional image into a number of adjacent blocks, wherein each of the adjacent blocks is associated with a different region of the display surface; and directing the light diffracted by the EASLM to sequentially write the adjacent blocks to the display surface.
