A holographic head up display (HUD) for a vehicle to display an image holographically on a curved display surface such as a windshield comprising a spatial light modulator (SLM) to display a hologram, an illumination system to illuminate said displayed hologram, projection optics to project light from the hologram onto the display surface to form an image and a processor configured to process the image data to generate hologram data for display on the SLM to form the image. The HUD further comprises a non-volatile data memory coupled to said processor to store wavefront correction data for the display surface, wherein the processor is configured to apply a wavefront correction responsive to the stored wavefront correction data when generating the hologram data to correct the image for aberration due to a shape of said display surface. |
