We describe a holographic image projection system for projecting an image at an acute angle onto a surface, the system including: a spatial light modulator (SLM) to display a hologram; an illumination system to illuminate said displayed hologram; projection optics to project light from said illuminated displayed hologram onto said surface at an acute angle form said image; and a processor having an input to receive input image data for display and an output to provide hologram data for said SLM, wherein said processor is configured to: input image data and convert this to target image data; generate from said target image data hologram data for display as a hologram on the SLM to reproduce a target image; and wherein said target image is distorted to compensate for said projection of said hologram at an acute angle to form said image.
