1. A holographic display comprising light sources in a 2D light source array, lenses in a 2D lens array, a spatial light modulator (SLM) and a beamsplitter, in which there are m light sources per lens, and the light sources are in m-to-one correspondence with the lenses, where the beamsplitter splits the rays leaving the SLM into two bundles, one of which illuminates virtual observer windows for m left eyes (VOWL) and the other illuminates virtual observer windows for m right eyes (VOWR), m having a value of greater than 1.
