Abstract
There is provided a driver for a spatial light modulator. The spatial light modulator comprises [m×n] pixels. The driver is arranged to receive input holograms each comprising [x×y] pixels, wherein m≥x and n≥y. The driver is further arranged to drive the spatial light modulator to display thereon output holograms each comprising [m×n] pixels by tiling each input hologram onto the pixels of the spatial light modulator to form an output hologram corresponding to each input hologram using a tiling scheme. The driver is arranged to use a first tiling scheme to display a first output hologram and a second tiling scheme to display a second output hologram. Each output hologram comprises a plurality of tiles of the input hologram. Each tiling scheme defines the size of each tile and the position of each tile on the pixels of the spatial light modulator.
