1. A holographic head up display (HUD) for a vehicle to display an image holographically on a display surface of the vehicle, the HUD comprising:

  • 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 display surface to form said image; and

    a processor having an input to receive image data for display and having an output for driving said SLM, and wherein said processor is configured to process said image data to generate hologram data for display on said SLM to form said image on said display surface;

    said HUD further comprising a non-volatile data memory coupled to said processor to store wavefront correction data for said display surface; and

    wherein said processor is configured to apply a wavefront correction responsive to said stored wavefront correction data when generating said hologram data to correct said image for aberration due to a shape of said display surface.
