- 1 - ABSTRACT OF THE DISCLOSURE In a conventional head-up display for a curved windscreen, the light beam containing the image of the display must be pre- distorted before it impinges on the windscreen so that a collimated, non-distorted image is reflected to the driver. The invention uses a transmission holographic system in place of correcting optics and consists of two holograms, one of which corrects for chromatic aberration to permit the use of a filtered incoherent source to illuminate the display.
