The light source is arranged to illuminate at least one region of the spatial light modulator with an input beam such that the input beam is spatially modulated by the spatial light modulator in accordance with the hologram to form a holographic reconstruction. The assembly is arranged to move at least one of the input beam and the spatial light modulator relative to the other.
