Abstract
A holographic display includes a spatial light modulator (SLM), a light source arranged to illuminate the SLM, and replay optics arranged to focus light reflected from the SLM to present a three dimensional image. The light source appears substantially at a zeroth order point of the replay optics, such that light from the light source is directed through the replay optics before illuminating the SLM.
